P5, P9, P11, P22, P91 and P92 Pipes

Chrome-molybdenum alloy steels for high pressure and temperature.

They follow the ASTM A335 standard, in the category of chrome-molybdenum alloy steels, known for withstanding extreme pressures and high temperatures.

Used in boilers, heat exchangers, piping systems and high-pressure, high-temperature processes such as power plants and refineries. The difference between the grades lies in the chromium and molybdenum contents.

• ASTM A335 standard
• Chrome-molybdenum steels
• P5: 5% Cr / 0.5% Mo · P9: about 9% Cr
• Boilers, heat exchangers and refineries
