EXTSW  12.18 mm ID x 17 mm OD x 60.12 mm thick 316 Stainless Shaft Spacer Actual size .479" ID x 669” OD x 2.367" long (+/- .003" on all dimensions) .030 inch Radius OD / Countersunk ID (no sharp edges) Made in USA on a CNC lathe Just contact me if you need a custom size washer. 316 Grade Alloy Stainless contain a higher percentage of nickel than 304SS. The resultant composition gives a much improved corrosion resistance in many aggressive environments. The molybdenum addition ensures more resistance to pitting and crevice corrosion in chloride-containing media, sea water and chemical environments such as sulfuric acid compounds, phosphoric and acetic acids. The lower rate of general corrosion in mildly corrosive environments gives 316 SS a good atmospheric corrosion resistance in polluted marine atmospheres. 316 SS offers good strength and creep resistance and also possesses excellent mechanical and corrosion-resistant properties at sub-zero temperatures.
