SS 304L Fasteners has excellent corrosion/ oxidation resistance thanks to the chromium content, where weld annealing is only necessary in applications where stress loads are excessive. The values of Alloy 304L Washers may be adjusted by control of specific melt chemistry and process variables to obtain discrete ranges of strength and ductility.

304L Stainless Steel Fasteners is readily formed in the annealed temper. The low carbon chemistry of Grade 304L Screws combined with an addition of nitrogen enables it to meet the mechanical properties of Grade 304.
