Stainless Steel 316/316L

Grade Summary: Grade 316 is a standard molybdenum-bearing grade, the second most commonly sought after grade next to grade 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance in chloride environments. Grade 316L (L= low carbon) )  is  the same as the above except it has an extra-low-carbon analysis, the advantage of which is that it precludes any harmful precipitation in the 800º F to 1500º F range that might result from welding heavier sections. Therefore 316L is extensively used in heavy gauge welded components. Typically there is no price difference between 316 and 316L stainless steel.

Typical Applications: Pump shafts and parts in machinery used to process paper, textiles, chemicals  and pharmaceuticals. In aircraft applications, used for parts requiring low magnetic permeability and good corrosion resistance.
