431 high temperature resistant stainless steel pipe is a stainless steel pipe with high strength, corrosion resistance and wear resistance, which is widely used in industrial fields with high load and harsh environment. The chemical composition of 431 stainless steel pipe mainly includes carbon (C), chromium (Cr), nickel (Ni), manganese (Mn) and other elements. The high chromium content makes it have excellent corrosion resistance, while the medium carbon content provides high strength and hardness.
Application field and high temperature resistance
431 high temperature resistant stainless steel pipe can still maintain high strength and oxidation resistance in high temperature environment, and the maximum use temperature can reach 650°C.
Aerospace: used to manufacture key components of aircraft and rockets, such as engine components and turbines.
Chemical industry: used to manufacture equipment and pipelines for chemical media such as nitric acid and acetic acid.
Marine engineering: used for key structural parts of offshore platforms and ships.
Automobile manufacturing: used to manufacture valves and exhaust valves and other parts of automobile engines.
