What is P235GH material equivalent?

P235GH is a European standard pressure vessel steel grade commonly used in the production of heat exchangers, boilers, and other pressure vessels. It is specified in EN 10028-2, which covers non-alloy and alloy steels for elevated temperature service.

Here are some key features of P235GH steel:

Chemical Composition: The chemical composition of P235GH typically includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and trace amounts of other elements. The exact composition may vary depending on the manufacturing process and specific requirements.

Mechanical Properties: P235GH has specified minimum yield strength of 235 MPa (or approximately 34,000 psi) and minimum tensile strength of 360-480 MPa (or approximately 52,200-69,600 psi). It offers good weldability and high thermal conductivity.

Elevated Temperature Service: P235GH is designed to withstand elevated temperatures and is suitable for use in applications where high operating temperatures and pressure conditions are encountered. It exhibits good creep resistance and thermal stability.

Pressure Vessel Applications: P235GH is commonly used in the production of pressure vessels, heat exchangers, boilers, and other components that operate under high temperature and pressure. It meets the requirements for materials used in pressure vessel construction and is widely used in various industries, including petrochemical, power generation, and oil and gas.

Overall, P235GH is a versatile steel grade that provides good mechanical properties and is specifically designed for elevated temperature and pressure applications. Its suitability for pressure vessel construction makes it a popular choice in industries where reliable and durable equipment is required.
