Pipe: A335/SA335
Forged/Bored Pipe: A369/SA369
A335/SA335 P5 is a seamless ferritic alloy-steel pipe used for high-temperature applications. These pipes are versatile and can be used to transmit water, oil, and natural gas.
Key to the composition of chrome moly alloy P5 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 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.
