321 Stainless Steel Welded Pipe 4-200mm OD with 17-19% Chromium for High Temperature Applications
321 high temperature resistant stainless steel pipe features excellent performance in high-temperature environments with chromium content of 17-19%, nickel content of 9-13%, and titanium stabilization to prevent intergranular corrosion. This welded steel pipe maintains superior mechanical and chemical properties across demanding industrial applications.
- High temperature resistance: Maintains mechanical and chemical integrity at elevated temperatures
- Corrosion resistance: Withstands acids, alkalis, salts and chemical substances
- Oxidation resistance: Prevents surface oxidation and corrosion
- Tensile strength: Retains excellent tensile properties under high temperatures
- Processing versatility: Suitable for cold forming and hot forming operations
Aerospace (engine combustion chambers, tail nozzles), Petrochemical (high-temperature pipelines, reactors), Energy (nuclear power plant components), Automotive (exhaust systems, fuel systems), and Medical equipment (surgical instruments, sterile environment components).
