SS 310 Washers

SS 310 Washers are thin, flat, disc-shaped fasteners with a central hole, primarily used to distribute the load of a threaded fastener (like a bolt or nut) over a wider area. In high-temperature bolting, they are crucial for preventing damage to the flange or component surface during tightening and maintaining a stable joint despite thermal expansion. Made from high-chromium and high-nickel austenitic stainless steel (UNS S31000), this material is specifically designed for extreme heat service, providing excellent resistance to oxidation and scaling up to 2000°F (1093°C). The high alloy content ensures that the washer retains its mechanical integrity and dimensions under prolonged thermal stress. Zeron Fasteners manufactures and supplies reliable SS 310 Washers in various types (e.g., Flat, Spring, Belleville), often conforming to specifications like ASTM F436 (for hardened washers) or DIN 125, ensuring the integrity of critical bolted connections in furnace linings, heat exchangers, and other high-temperature industrial equipment.
