What is P265GH steel?

P265GH is a European standard pressure vessel steel grade. Here are some key features and information about P265GH steel:

Composition: P265GH is a carbon steel with a chemical composition that includes primarily iron (Fe), carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), and traces of other elements.

Pressure vessel steel: P265GH is specifically designed for use in pressure vessels, boilers, and heat exchangers. It is often used in the oil, gas, and petrochemical industries where high-temperature and high-pressure conditions are encountered.

High-temperature properties: P265GH can withstand elevated temperatures and has good creep resistance, making it suitable for applications involving operating temperatures up to 400°C (752°F).

Mechanical properties: P265GH exhibits good mechanical properties, including high strength and ductility. The exact values depend on the thickness and heat treatment condition.

Weldability: P265GH is readily weldable using common welding methods. However, it is important to follow appropriate welding procedures and ensure proper preheating and post-weld heat treatment when necessary.

Compliance: P265GH conforms to the European standard EN 10028-2, which specifies the requirements for flat products for pressure purposes. It is classified as a non-alloy quality steel.

P265GH is a widely used and well-established steel grade for pressure vessel applications due to its good combination of mechanical properties, high-temperature resistance, and weldability.
