ASTM A335 is a specification for seamless ferritic alloy-steel pipes,grade P22 is a chromium-molybdenum (Cr-Mo) low-alloy steel, designed for high-temperature service, widely used in power plants, refineries, and petrochemical industries.
Element:
Low carbon for weldability.
Chromium (Cr) provides oxidation resistance.
Molybdenum (Mo) enhances high-temperature strength and creep resistance.
P22 offers a good balance of strength, weldability, and creep resistance, making it a preferred choice in power and petrochemical industries.
