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.
