ASTM A335/ASME SA335 P22/UNS K21590 Alloy Steel Seamless Pipe for High Temperature Service
Overview:
A335/SA335 Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with addition of chromium, molybdenum, and sometimes vanadium. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance, and it also enhances the corrosion resistance of steel and inhibits pitting. Grade P22 is used for high temperature service applications and is tolerant to variations in its microstructure.
