Product Name : ASTM A312/A213 Stainless Steel SS TP 321 Pipes & Tubes Specification : DIN 1.4541
Stainless Steel 321 Welded Pipes is similar to Type 304 stainless steel, however, it contains a Titanium addition of at least five times the carbon content. This addition is made to reduce or eliminate chromium carbide precipitation – resulting from welding or exposure to high temperatures. Stainless Steel 321 Tubing resistance to sensitization, coupled with its higher strength at high temperature makes it suitable in application where Stainless Steel 304 will become sensitized, or where Stainless Steel304L has insufficient hot strength.
