ASTM A 335 P-22/ T-22


ASTM A335 P22 Seamless Pipe is also known as the 2 ¼ chrome pipes. The material is a carbon steel with added chromium, molybdenum and vanadium at some instances. The chromium content is responsible for the added high temperature strength in the ASME SA335 Grade P22 Alloy Steel Pipe SCH 40 and other schedules.
The material has high creep resistance and corrosion resistance. The molybdenum content provides the creep resistance and the pitting resistance to the pipes. The ASTM A335 P22 Pipe is applicable in high temperature services. The high temperature service ability comes from the composition. The composition of the ASTM A335 P22 Welded Pipe has carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum in it.
