a355 p91 alloy steel pipe

ASTM A335 P91 seamless pipe is made of high-quality carbon steel with excellent mechanical properties. Its minimum tensile strength is as high as 415MPa and its minimum yield strength is 205MPa, which allows the material to maintain excellent performance under high pressure and high temperature environments. In addition, ASTM A335 P91 seamless pipe also has high toughness and high wear resistance, which can maintain stable performance in various harsh environments.

ASTM A335 P91 Seamless steel pipe has a specific chemical composition, including carbon content between 0.05% and 0.15%, manganese content between 0.30% and 0.60%, phosphorus content up to 0.025%, and sulfur content The maximum is 0.025%, the silicon content is between 0.50% and 1.00%, the chromium content is between 1.00% and 1.50%, the molybdenum content is between 0.44% and 0.65%, and the nickel content is between 0.50 and 0.50%. %, and the vanadium content is between 0.18% and 0.25%.ASME A335 Alloy Steel P91 Pipe is a seamless ferritic Alloy Steel Pipe specifically designed for high temperature applications. This steel pipe is designed to withstand the stress and corrosion of high-temperature environments. The ASME A335 specification covers several grades of ferritic alloy steel pipe, including P11. These steel pipes are commonly used in power generation, petrochemical processing, and other industrial applications where high temperatures and pressures exist.

We can also supply Carbon Steel Pipe, APl Line Pipe, Galvanized Pipe in any form.
