Stainless steel 321 Welded Pipe is similar to type 304 stainless but with a titanium addition of at least five times the carbon content. SS 321 Seamless Pipe cannot be hardened by thermal treatment. SS 321H Pipes is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000 – 1600 Degree F temperature range. Stainless steel 321 Pipes is readily welded by all common methods including submerged arc. We are a distinguished supplier and stockiest of SS 321 / 321H Pipe, where we offer the same at standard and customized sizes.
