309s Stainless Steel Sheet Introduction
309s Stainless Steel Sheet is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high-temperature strength, and creep resistance. The lower nickel content of Stainless Steel 309, compared to Stainless Steel 310, improves its resistance to hydrogen sulfide (H2S) attack at high temperatures.Stainless Steel 309S is used for its high-temperature oxidation resistance and/or resistance to H2S attack for applications such as furnace parts, firebox sheets, high-temperature containers, catalytic converters, and exhaust systems.
What is 309S stainless steel? General Properties
Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. 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).
What is the difference between 304 and 309 stainless steel?
Alloy 309/309S is an austenitic heat resisting stainless steel. 23% chromium, approx. 5% more than 304 stainless steel gives Alloy 309/309S an edge over 304 stainless steel when it comes to general corrosion resistance at elevated temperatures.
