P265GH Steel – Heat Resistant & Non-Alloy

What is P265GH? Grade P265GH is the Heat Resistant Pressure Vessel Steels defined in the EN 10028 system. It is a non-alloy steel. The material is designed for high temperature applications. Therefore it is mostly utilized in high temperature applications in the oil and gas sector, chemical processing industries and petrochemical sectors.

It is a main fabricating material of boilers and pressurized vessels. It is normalized by keeping it against a temperature of 890 to 950°C without holding; the heating is passed on through the thickness of the plate.

What is EN 10028? P265GH is identified in the standard EN 10028. It is a European material standard for “Flat products made of steels for pressure purposes”. Moreover the standard covers “Non-alloy and alloy steels with specified elevated temperature properties”. The standard was published in the year 2009.
