SA335/A335 P9 Seamless Alloy Steel Pipe
SA335/A335 P9 seamless alloy steel pipe is a kind of chromium-molybdenum alloy heat-resistant steel for high temperature use,
SA335/A335 P9 is equivalent to UNS K90941.It has good oxidation resistance, high temperature strength and sulphide corrosion
resistance. This material is widely used in petroleum refining units in the high temperature, high pressure, flammable, explosive
pipeline, especially the heating furnace direct heat pipe, the medium temperature up to 550 ~ 600 ℃.
