Ninthore Overseas is one of the Leading Manufacturer And Exporter Of Stainless Steel 316 Washers, where additional mechanical or physical properties may also need to be considered to achieve the overall service performance requirements. Commercially produced steels, using current steelmaking methods, Stainless Steel 316 Flat Washer are often produced as the low carbon type as a matter of course due to the improved control in modern steelmaking.

Consequently, these SS 316L Lock Washer are often offered to the market ‘dual certified’ to both grade designations as they can then be used for fabrications specifying either grade, within a particular standard. Stainless Steel 316 Sealing Washers is a term coined early in the development of these steels for cutlery applications. It was adopted as a generic name for these Stainless Steel 316L Split Washer and now covers a wide range of steel types and grades for corrosion or oxidation resistant applications. SS 316 Slot Washer are iron alloys with a minimum of 10.5 % chromium.

Other alloying elements are added to enhance structure and properties of these SS 316L Machine Washers such as formability, strength and cryogenic toughness. The main requirement for Stainless Steel 316 Star Washers is that they should be corrosion resistant for a specified application or environment. The selection of a particular “type” of these SS 316L Spring Washers must initially meet the corrosion resistance requirements.
