0.08 C, 2.00 Mn, 0.045 P, 0.030 S, 1.00 Si, 18.00/20.00 Cr, 8.00/10.50 Ni, Bal. Fe

CarTech 304 stainless is the most widely used chromium-nickel austenitic stainless steel. It is nonmagnetic in the annealed condition and becomes slightly magnetic when cold worked. It has excellent fabricability and weldability characteristics. Nonhardenable by heat treating.

CarTech 304L Stainless

Composition (Nominal)
0.03C, 2.00 Mn, 0.045 P, 0.03 S, 1.00 Si, 18.00/20.00 Cr, 8.00/12.00 Ni, Bal. Fe
Low-carbon content minimizes problem of carbide precipitation during welding and has permitted this alloy’s use in corrosive service in the as-welded condition.
