ASME SA335 P12 alloy steel pipe is a high-temperature chromium-molybdenum alloy steel for boilers, with a typical composition of 1Cr-0.5Mo. It has good oxidation resistance and high-temperature steam corrosion resistance.
SA335 P12 high-pressure steel pipe is widely used in large-diameter pipelines and corresponding high-temperature headers of large-capacity thermal power generating units.
The implementation standards of ASTM A335 P12 steel pipe include DIN17175-79, JISG3467-88, JISG3458-88, GB5310-2008, GB9948-2006, ASTMA335/A335m and ASTMA213/A213m, etc.
