P235GH steel is a heat-resistant pressure vessel steel defined in the EN 10028 system. It is similar to P265GH but with a lower content of Carbon and on the other hand with higher content of Manganese.

P235GH steel has lower yield and tensile strength compared with P265GH. It is also non-alloy steel. The material is also designed for high-temperature applications. This material is said to have good cold-working as well as hot-working characteristics. Therefore it is utilized in pipes transporting hot liquids.

Equivalent Material Grades in Other International Standards:

The equivalent grade of this type in ASME/ASTM is A285 grade C

In the DIN standard, the corresponding material is 1.0345-type steel.

In British BS standard, the corresponding material is 141-360 type steel.

In the Japanese JIS standard, the corresponding material is SB410-type steel.

P235GH is the designation alloy in the European standard, also referred to as A285 grade C steel in ASTM A285 / A285M standard.
