Regular Size of our 309S Stainless Steel Plate in stock

Stainless steels are a family of iron based alloys that contain a minimum of 10.5% chromium (CR). The presence of chromium creates an invisible surface film that resists oxidation and makes the material passive or corrosion resistant (stainless). There are multiple families of stainless steel which are designed for various applications and uses. Stainless grades can be further modified to meet various processing, corrosion, temperature and strength conditions.

About 309/309S Stainless Steel 

Type 309 (UNS S30900)
Description
Type 309 is a high temperature chromium nickel austenitic stainless steel that resists oxidation at temperatures up to 1900˚F in dry air at constant temperature. Under thermal cycling conditions this grade resists oxidation up to a temperature of approximately 1850˚F. Type 309 has good sulfidation resistance but low resistance to carburization and should not be used in highly carburizing atmospheres. Type 309 is non-magnetic in the annealed and cold worked conditions and is as resistant to corrosion as Type 304/304L.

Physical properties of 309/309S stainless steel

Features

• Corrosion Resistance: 309 stainless stands-up excellently in a range of atmospheric environments even when exposed to corrosive elements.
• Heat Resistance: Can be hot worked at 1177C and then can be quenched rapidly.
• Easy to weld by using fusion or resistance welding methods (preferably not oxyacetylene though).
• Can be headed, upset, drawn, and stamped even though it has high work hardening rate.

Applications
The 309 can be applied to a range of applications including a variety of accessories and equipment such as boiler baffles, furnace components, oven linings, fire box sheets, and other high temperature containers.
