(1 pc) EXTSW 1/2" ID x 3/4" (.738") OD x 2.500" thick 316 A4 Stainless Shaft Spacer. Actual size .507" ID x .738” OD x 2.500" 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.
