What is A-36 Steels? A-36 steel is a structural billet steel for structural applications. A-36 is a material grade and designation defined in ASTM A36/A36M-08 standard. ASTM A36/A36M-08 is an international material standard for billet steel for general structural usage. Fe-510 steel can be compared with this type of steel.
Dimensional Characteristics of A-36 Steels: The applicable thickness for this A-36 material as defined in the ASTM A36/A36M-08 starts from 10 mm to 60 mm.
The Chemical Composition of A-36 Steels: ASTM A36/A36M-08 defines the chemical composition of A-36 steels as under:
Maximum percentage of Carbon (C) is 0.290.
Maximum percentage of Manganese (Mn) is 0.90.
Maximum percentage of Phosphorous (P) is 0.040.
Maximum percentage of Sulphur (S) is 0.050.
Maximum percentage of Silicon (Si) is 0.350.
Remaining is iron (Fe) percentage and with few negligible impurities.
Mechanical Properties of A-36 Steels: The tensile strength of the A-36 Steels is expressed in Newton per millimeters and it must be at-least 400 N/mm2 (MPa) and maximum can be 550 N/mm2 (MPa). The yield strength is minimum 250 N/mm2 (MPa). The minimum percentage ranges for elongation is 23%.
