Detailed Product Description

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.

P220.05-0.150.3-0.60.0250.0250.51.9-2.60.87-1.13

 

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
