A312 TP321/321H Seamless Stainless Steel Tube Pipes 1/8"-12" OD 0.6-12.7mm Thickness

321 Stainless Steel is a titanium-stabilized chromium nickel austenitic stainless steel with excellent intergranular corrosion resistance and high-temperature strength. It maintains high mechanical strength and creep resistance in high-temperature environments, suitable for long-term use at elevated temperatures.

Alloy 321H features higher carbon content (0.04-0.10%) for enhanced creep resistance and strength above 1000°F (537°C), providing superior oxidation resistance for extended high-temperature applications.
