What is Commercial Quality Cold Rolled Steel? The commercial quality cold rolled steel is a type of steel that can be used commercially for forming purposes that can also include shearing of a metallic sheet. Common operations that can be done on such steels are:

  • Bending
  • Curling
  • De-cambering
  • Blanking
  • Shaping
  • Lancing
  • Piercing
  • Notching

Why is SPCC material called cold rolled Steel? When a material grade is specified as cold rolled steel, it means it has been subjected to a manipulative process of cold rolling in which a metal bar is passed through high tension rollers below the re-crystallization temperature of the steel. The roller does not only decrease the thickness of the sheets but also refines the grain structure and hardens the steels.  SPCC steels add more good dimensional properties than SPHC Steels. Also, after the cold rolling process there are some additive processes like rewinding, annealing, and then skin passing to make a complete SPCC material with bright finish.

Available Forms in Market: Following are the available forms of SPCC steels in the global market:

  • Mill Edge Coils

  1. Ranjeet says:

    JIS designation of SPCC is JIS G 3141 but in Chemical compositon it is mentioned JIS G 3131.

    Is it same in chemical composition.

    Overall information is much better &; easy to understand
    Thank you

    1. Lawrence says:

      JIS G 3131 and JIS G 3141 chemical composition is different

      1. ŞENOL YILDIRIM says:

        Our customer spec. is SPCC , and technical standart JIS G3141. But another requiremend in the technical drawing HV 0,2 must be 420 min – 800 max. How is it possible ? Could you please help about this issue? When we tested our equivalent grade ( DIN EN 10130 / DC 01 ) the hardness result is only 116 . Coud you propose steel sheet for 1 mm thickness, supply this requirements?

    2. nilesh says:

      i want to know what will be the min – Max Hardness for SPHC & SPHE material.

    3. Musarrat Siddiqui says:

      because commodity is changed. G 3141 is used for steel sheets and G 3131 is used for chemical.

      hope this will help for your understanding.

    4. Daniel says:

      Can someone tell me what is the heat resistance of the SPCC? I want to use this steel for accessories to my wood burning fire pit and the heat at the core of wood burning fire pit will reach 1100c. I worry about the rust and corrosion from humidity found in Canadian summers…. how long can I expect 2mm thick SPCC to last before rusting in a humid environment?

    5. Ahmed Ammar says:

      Is the SPCC similar to DC01 or harder?
      I just need soft material

      1. serdar demir says:

        SPCC and DC01 are the same material, norm is only different related with country.

    6. Jitendra singh says:

      can you provide the JIS G 3141 standard to me.

  2. Adam Rudolf says:

    Thanks for question.

    Actually JIS G 3141 is a specification for cold roll material, and JIS G 3131 is a specification for hot roll steel. The chemical composition of SPCC steel is similar to SPHC steels, thats why the chemical composition of JIS G 3131 is referred, however JIS G 3141 is also same.

  3. Ashish says:

    Is SPCC better than SS304? and how does it prevent rust / corrosion / oxidation… powder coating or something else??

    Thank you

    1. Andrew Michael says:

      Ashish Thank-you for your question

      For your first question, I must say It depends on the application. SS304 is stainless steel where as SPCC is a mild steel. SS304 steel is utilized in chemical, dairy, food processing, cryogenic vessels, petrochemical, kitchenware and fertilizer industries. SS304 steel is utilized in areas where environment is highly corrosive & SS304 steel is inert in that case due to high rust resistance. SPCC steel is a commerical quality steel and is utilized in applications mentioned in above article.

      SPCC steel is prone to rust & is prevented by oiling on its surface.

  4. jawad afzal sheikh says:

    we are manufacturers of perforated steel sheet and use cold rolled sheet with specification SPCC-SD . can we use SPCC-1B for the same purpose .

    1. Andrew Michael says:

      SPCC-1b is a bright finish material & it is full hard, hardness is almost greater than 85 HRB, right now you are using a material below 65 HRB. So if you for a full hard material it can affect your process parameters and the final product & the mechanical properties like Tensile strength will be higher with lower elongation. The second thing is the bright finish if you for the SPCC-SB that is mechanical properties are same but the finish is bright then if you have no coating application like chroma-ting then it is okay to go with bright finish surface.

    2. Lawrence says:

      SPCC-1B can be use also, depending on your processes. SPCC-1B almost have no elogation (1% – 2% only). If your processes doesn’t required any drawing then should be no problem. Regarding on coating, SPCC-1B material also can be use in GI or prepainted process.

  5. Yaseen Raza says:

    What are the Hall-Petch Equation constants for SPCG steels?
    If they are not derived, how can we work to obtain them

    1. Andrew Michael says:

      Dear Yaseen Raza,

      thank-you for your question and apologies for delayed reply as I am a freelance and was employed by a company these days, now I am back again.
      Since SPCG steel is dead mild steel. Its Hell-Petch equation constant should be below 0.70
      We can obtain the value this of constant by using Hell-Petch equation, stress strain diagram for SPCG material and calculating the average grain diameter with the help of ASTM grain size chart. Once we get yield stress, starting stress from the stress strain diagram, and the value of average grain diameter from ASTM grain size chart, we can put these variables in Hell-Petch equation to calculate Hell-Petch equation constant.

  6. Fabian says:

    Hello, could you help me please?
    I would like to ask that what is the difference between JSC270C and Jsc270CC. Where can I find any information about it?

    1. Andrew Michael says:

      We have forwarded this request to our R & D publishing department. They will see whether they can publish articles for these grades or not. Basically these are commercial quality cold rolled steels with low carbon content.

    2. Lawrence says:

      JSC270C steel grade actually refer to JFS A 2001 standard which is usage for automotive.

  10. rAJ says:


    1. Andrew Michael says:

      This is a Japanese term, you won’t find correct full meaning of abbreviation in English, but all that is available on internet is not true. One of the incorrect example of full meanings provided by some internet buddies are Standard Processed Commercial Cold Rolled Steels.

  11. Yogen says:

    What is the difference between SPCC-SD & SPCC 2T
    Can i use the SPCC-SD in place of SPCC-2T

    1. Adam Rudolf says:

      SPCC-SD is a dull finish standard temper grade which cannot be used for SPCC-2T which is half hard material with tensile strength guaranteed.

  12. Yee says:

    Hi, which cold roll material best for structural use in coated sheet (GI)? SPCC-1B or SPCC-SD?

    1. Andrew Michael says:

      First of all SPCC-SD is not used for coating. Secondly SPCC-1B is used for this purpose. SGC570 grade galvanized steel is the best in structural quality

  13. ravi says:

    Whats the difference between normal Mild steel and SPCC? Can normal MS can be used in place of SPCC in application of tongued washer in couplings?

    1. Andrew Michael says:

      SPCC is dead mile steel, it means it has lower carbon content that normal Mild steel. So if your application has a lower strength requirement you can use it but not in application when you need higher strength.

  14. mathavan says:

    Im looking for SPCC- SD cold rolled supplier with Sirim Certificate..Anyone can help me ?

    1. Andrew Michael says:

      I think you have to see some supplier/manufacturer in Malaysia, there are many manufacturers in Malaysia and they will be surely operating under SIRIM so you can have SIRIM certificate as well while purchasing from their.

    2. Lawrence says:

      there a few manufacturer, which countries u prefer?

  15. Khilji says:

    Dear if you please clarify that in any grade of cold rolled steel sheet which chemical and mechanical compositions or specs are the best for nickel or chrome coating after drawing the sheet to give it a shape of any auto part..Please do assist

    1. Andrew Michael says:

      For drawing you better use a drawing quality product like SPCD, SPCE, SPCF and SPCG steels. Now if you need deep draw you can use SPCF and SPCG steels. But if you are in need of normal drawing process you can use SPCD and SPCE steels. As far as coating is concerned there should be any problem while coating any of these steels.

  21. Eka Teja says:

    Andrew, Why spcc steel is good for stator/rotor lamination? So far I knew lamination sheet must use silicon sheet. I need to know what the difference of both?

  22. Roshen T says:

    Hi Adam, how are you? Great article, I do have a question (maybe not related to the above) but hoping you might have some idea or advise. With regards to international steel standards (ASTM,EN,DIN,BS,JIS,etc..), how do they co-relate to AS/NZS steel standards in term of compliance? I’m pretty sure you have heard about ACRS. Can I still purchase steel off any manufacturing countries in the world who is not listed as a certified steel manufacturer on ACRS website? By the way, I’m from New Zealand. Cheers!

    1. Adam says:

      I don’t know what compliance issues you face in New Zealand, however for application purpose if you are using some grade of steel listed in AS/NZS steel standards, you should see which of the corresponding steel is there in other international standards like ASTM or JIS, that may have similar chemical composition, mechanical properties and dimensions. Also the manufacturing process should be the same. Then you can of-course purchase material from there countries as well that matches or suffice your product requirements.

  23. Ahmad Khashai says:

    When ever I want to purchase Tinplate – I find two types of steel used MR and SPCC. Can anybody tell me what is tthe difference between them
    Thank you

    1. Andrew says:

      SPCC steel is the commercial quality as already discussed in the article. MR is a steel type which is defined as low in residual elements that has high corrosion resistance, extensively used in general applications

  24. Jesi says:

    Dear ,

    What is the difference between SPCC and SPCE


    Its SPCC SD and SPCD same?
    please explain soon

    1. Haniff Adam says:

      Hi just to help this question.

      SPCC SD = Cold Rolled commercial grade standard dull surface.

      SPCD = Cold Rolled drawing grade.

      Thus both are different.

      Thank you.

  26. Carlos says:

    Hi Adam.

    i have a question about equivalencies between SPCC and Ds type B material ( ASTM) its the same??

  32. Braam says:

    When receiving JIS material, does it have a heat number or cast number and will you get a material certificate for this type of material.

    1. Andrew says:

      You should receive a mill test certificate and mil test certificate can contain heat and cast numbers depending on the manufacturer’s traceablity system.

  33. Braam says:

    I have ordered JIS material from a supplier, requesting a material certificate for the material being delivered. It was said that you don’t get material certificates for this type of material. I want to confirm

    1. Andrew says:

      The supplier should give you mill test certificates or material certificates.

  34. Gagan says:

    Can anyone tell is spcc and swpa are same or diffrent?

    1. Andrew says:

      SWPA is a spring material and thus it is obviously different

  35. Adelyn Siow says:

    Any different between SPCC-SD and SPCC-S??

    1. Andrew says:

      “-S” in SPCC-S refers to tempering grade, which is in this case is skin passed hrough skin passing mill. The “D” of SPCC-SD refers to dull finish.
      SPCC-S is tempered skin pass grade
      SPCC-SD is tempered skin pass with dull surface finish. Hope this clarifies

  36. David says:

    What is the difference between JIS 3141 and ASTM 513?

  37. Rajdeep Kavaiya says:

    i want to use this sheet in water with 1000TDS and 90degree temperature, is that possible with this metal for long life?

    1. Andrew says:

      SPCC steel is a commerical steel and it will catch rust immediately in such water.

  38. Bhavesh Shah says:

    Is SPCC-S suitable for conversion coating like zinc phosphating followed by powder coating.

    1. Andrew says:

      Usually SPCC-S i.e. skin passed steel is normally not used for coating purposes directly as in the case of hot dip galvanization. SPCC-AS annealed grade other than skin passing may be used following expert opinion on zinc phosphating.

  39. Deepika says:

    what is spcct? if can we get sheet material?what is the equivalent material ?

    1. Andrew says:

      SPCCT is a material with tensile strength quaranteed. For sheet material you will have to refer to the same grade i.e. SPCCT
