P235GH is a European standard pressure vessel steel grade. It is a non-alloy steel with specified elevated temperature properties, which means it is suitable for use in high-temperature applications such as boilers, pressure vessels, and heat exchangers.
The “P” in P235GH stands for “pressure,” and the number “235” refers to the minimum yield strength of the steel in megapascals (MPa). The “GH” suffix indicates that the steel is suitable for elevated temperature service.
P235GH is commonly used in industries such as oil and gas, chemical processing, and power generation. It is also used in the manufacturing of heat exchangers, steam boilers, and pressure vessels. P235GH is known for its excellent weldability and formability, making it a popular choice for fabrication and construction projects.
The chemical composition of P235GH is as follows:
– Carbon (C): 0.16% max
– Manganese (Mn): 0.60-1.20%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.015% max
– Silicon (Si): 0.35% max
– Nickel (Ni): 0.30% max
– Chromium (Cr): 0.30% max
– Molybdenum (Mo): 0.08% max
– Copper (Cu): 0.30% max
– Nitrogen (N): 0.012% max
– Aluminum (Al): 0.020% max
The composition may vary slightly depending on the manufacturing process and the specific requirements of the application. However, these are the typical chemical composition ranges for P235GH steel.
