309S Heat Resisting Austenitic Stainless Steel

Introdução

Overview of 309S Heat Resisting Austenitic Stainless Steel

Alloy 309S (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications.

309S heat resisting austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic 304 aço inoxidável.

The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C).

Because of its high chromium and low nickel content, Liga 309 can be utilized in sulfur containing atmospheres up to 1832°F(1000°C).

Futures of 309S Heat Resisting Austenitic Stainless Steel

309S stainless steel is a low carbon, high chromium and molybdenum content alloy. The molybdenum content of 309S stainless steel provides excellent resistance to nitric acid at high temperatures. It also has good resistance to chlorine, sulphuric acid and phosphoric acid in concentration up to 65%.

The nickel content of 309S stainless steel makes it resistant to pitting attack in chloride containing environments.

309S stainless steel is suitable for use at temperatures up to 1300°C (2300°F).

The mechanical properties of 309S stainless steel are similar to those of 304L aço inoxidável, but the weldability is better than 304L due to its lower carbon content.
