ASTM A335 P9 Alloy Steel Seamless Boiler Tube For Power Plant Oil Refinery Petrochemical

ASTM A335 P9 Alloy Steel Seamless Boiler Tube, Power Plant , Oil Refinery , Petrochemical Application

Chrome Moly alloy P9 is the addition of chromium and molybdenum. 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. It also enhances the corrosion resistance of steel and inhibits pitting.
