Description of our 321 stainless steel coil

321 stainless steel introduce

Grade 321 Stainless Steel is much like 304, except the addition of titanium provides for better weldability. Grade 321 Stainless Steel alloy, also has better intergranular corrosion resistance and chromium carbide formation resistance than 304. Stainless steel type 321 can be used continuously at temperatures anywhere from 800° F to 1500° F. In its annealed form, 321 Stainless Steel alloy normally has a magnetic permeability less than 1.02 at 200H.

This is a standard austenitic 18/8 stainless steel grade, (304), but stabilized by Titanium. The titanium within means the stainless steel is intergranular corrosion resistant after heating, (between 425-900 degrees Celsius). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades. This grade is not, however, recommended for welding consumable, as the titanium component does not allow good transfer of heat across a high temperature arc.
