Ninthore Overseas is one of the Leading Manufacturer And Exporter of Stainless Steel 317L Washers, which cannot be hardened by heat treatment but they are magnetic. Stainless Steel 317L Flat Washers are sometimes called “non – harden able” and are the most common. SS 317L Lock Washers are alloys of chromium and iron with limited carbon contents that are generally below 0.12 %, where the chromium content can vary from 10.5 % to 30.0 %. Stainless Steel 317L Sealing Washers have good corrosion resistance (particularly to chloride stress corrosion cracking) but are generally not chosen for toughness.

Precipitation hardening Stainless Steel 317L Split Washers develops strength by precipitation hardening reactions as the result of heat treatment. With lower carbon levels, SS 317L Slot Washers have good corrosion resistance and are characterized by ease of fabrication. High strengths in Stainless Steel 317L Machine Washers can be developed at relatively low temperatures (500 Degree C – 800 Degree C) so distortion is minimized.

The chromium content in Stainless Steel 317L Star Washers is between 12.25 % and 18 %, with nickel levels of 3 % to 8.5 %. Molybdenum in SS 317L Spring Washers some grades is between 2 % and 3 %, with additions of aluminum, copper, rare earth elements and nitrogen. The martensitic structure results when chromium and higher levels of carbon in SS 317L Wire Spring Washers are added to iron.
