321 stainless steel Composition,321 stainless steel Welding

321 stainless steel is similar to Type 304 stainless steel, however, it contains a Titanium addition of at least five times the carbon content.

321 stainless steel is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C).

Type 321 is stabilized against chromium carbide formation by the addition of titanium.

321 stainless steel Welding
Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualifies welding of 321 and 347 with Grade 347 rods or electrodes; high silicon version of 347 is also pre-qualified for welding of 321.
