ANSON is the biggest stockists and suppliers of 321 stainless steel, available in plate, sheet,with the ability to meet profiling requirements and distribute globally from our facility in China.Type 321 is a standard austenitic 18/8 chromium nickel alloy with the addition of Titanium making it an excellent choice in elevated temperature environments.Used in particular applications within 450-850 degrees centigrade, 321 combines high strength with resistance to scaling and phase stability, Some typical areas of application are, furnace components, super-heater and afterburner parts, compensators and expansion bellows.

Stainless 321 is a heat resistant, titanium stabilized, austenitic alloy that’s commonly used for service in the 1000°-1600°F temperature range. 321 stainless is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800°-1500°F. Type 321 is similar to type 304 stainless but with a titanium addition of at least five times the carbon content.
