A335 P11 P91 ERW Tubes

A335 P11 P91 Welded Pipe Supplier-GNEE

GNEE Group can supply A335 P11 and P91 ferritic alloy steel pipes for high temperature applications. STM A 335 P11 steel pipe is a chromium-molybdenum alloy steel with high tensile strength, a minimum of 415 MPa and a yield strength of 205 MPa. The chromium content is 1% to 1.5%, and the molybdenum content is 0.44% to 0.65%. It has high toughness and can resist wear for a long time. ASTM A335 P91 steel material is a ferritic alloy with trace amounts of molybdenum and chromium added, which has anti-wear properties. Tensile strength, corrosion resistance and high temperature strength. ASTM A335 P11 and P91 are commonly used in power plants and chemical and petrochemical industries. GNEE Group supplies ASTM A335 P11 P91 chromium-molybdenum alloy steel pipes in sizes from 1/2″ to 54'' and wall thicknesses from SCH10 to 140mm. If you need it, you can contact us at any time to get a quote.
