ASTM A335 P22 Seamless Alloy Steel Boiler Pipes For Refineries Projects

ASTM A335 P22 Seamless Alloy Steel Boiler Pipes For Refineries Projects

ASTM A335 This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. ASTM A335 P22 is a chromium-molybdenum (Cr-Mo) alloy steel pipe for widely using in high-temperature and high-pressure applications, particularly in power plants, refineries, and petrochemical industries,etc.

Chemical Composition max%

Grade	Carbon	Manganese	Phosphorus	Sulfur	Silicon	Chromium	Molybdenum
P22	0.05-0.15	0.3-0.6	0.025	0.025	0.5	1.9-2.6	0.87-1.13

A balanced mix of alloying elements for strength, heat resistance, and corrosion resistance

(Cr enhances oxidation and corrosion resistance at high temperatures; Mo improves creep strength and high-temperature stability)

Mechanical Property

Grade	Yield Strength (Mpa)	Tensile Strength (Mpa)	Elongation (%)	High-Temperature Strength
P22	0.05-0.15	0.3-0.6	0.025	well up to 593°C (1100°F)

P22 pipes have excellent tensile strength, yield strength, and hardness. With high creep & oxidation resistance,Ideal for prolonged high-stress conditions;with weldability & durability, can easier to fabricate compared to higher-grade alloys.
