A213 T22 alloy steel pipe is a seamless alloy steel pipe for high temperature. It is mainly used in power station boiler superheaters, reheaters, economizers, air preheaters, water walls, centralized downcomers, main steam ducts, steam-water separators and Pipes and other components.What is the composition of A213 T22?
ASTM A213 Grade T22 Alloy Steel Seamless Tubes have a typical chemistry with additions of 1.90-2.60 Chromium and 0.87-1.13 Molybdenum. Bearing minimum tensile strength of 415 Mpa ASTM A213 Grade T22 Tubes have a minimum yield strength of 205 Mpa.In addition, the production process of A213 T22 alloy steel pipe includes hot rolling, cold drawing, etc. The steel pipe has a smooth surface, high quality grade, good mechanical properties and processing performance, and can be widely used in various high-temperature and high-pressure industrial environments.
