Stainless steel washers are versatile, exhibit excellent corrosion resistance, and possess counteractive properties when exposed to high temperatures. Here at Superior Washer, we maintain a full stock of washers made from the most in-demand grades of stainless steel in the 300 series. This includes 304L and 316L lower carbon stainless steels which have a max carbon content of .030. We also can manufacture washers from 410, 430, and 440 stainless. We keep a complete variety of thicknesses in stock and can customize washers according to your unique needs. For washers .010 thick or under, we stamp them from full hard 301 stainless steel. Passivation, DFAR compliance standards, and DFAR certifications are available upon request. 

We typically quote our stainless steel washers according to ASTM A240/A240M standards, but will quote according to the specs you provide in your RFQ. All of our washers are domestically manufactured, which is always noted on the Certificate of Compliance that comes with every purchase order. Our customer service staff is dedicated to providing you with everything you need when you place your order, so if you have questions or special requests, simply let us know.
