Specify the exact material grade and condition. These are RFQ options, not a stock list or a statement that every alloy meets every washer standard. Availability and technical suitability require confirmation.
| Requested grade | Confirm with your enquiry |
|---|---|
| SS 304 / 304L | Exact material specification, condition and required hardness or mechanical properties. |
| SS 316 / 316L | Corrosion environment, material condition, finish and specified washer performance. |
| SS 310 / 310S | Exact grade, service temperature and mechanical requirements; metal grade alone is not operating approval. |
| SS 904L | Stainless steel grade request; confirm product specification, manufacturing route and application. |
| HASTELLOY family | Exact alloy designation, material condition and test/documentation requirements. |
| Alloy 20 | Exact material specification and service conditions. |
| MONEL family | Exact alloy designation and required washer dimensions/mechanical properties. |
| INCONEL family | Exact alloy designation, temperature conditions and required mechanical performance. |
Washer geometry, hardness, spring condition or bendability must be specified separately from alloy name. Bolt and nut strength classes are not washer grades.
Specify Dimensions, Grade & Function Separately
For a circular washer, give inside diameter, outside diameter and thickness. Square and taper washers also need side dimensions and, where relevant, slope and orientation. Shims need thickness tolerance; spring, star and tab washers require their form and installation conditions.
A flat bearing washer is not automatically a locking device, and a dimensional standard does not establish material certification, stock availability or performance in every joint.
