P265GH Pressure Vessel Steel Plate

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.

Why P265GH called A516 grade 60 Steel? 
P265GH is the designation alloy in the European standard, also referred as A516 grade 60 in ASME/ASTM standards. Many manufacturers claim to be compliant with both specifications of EN 10028 and ASME/ASTM material A516 grade 60 steel.

Terminology
GH – is ideal for use in elevated working temperatures
NH – for moderate to high temperature service
NL1 – is ideal for use in low temperatures
NL2 – is ideal for use in especially low temperatures
