The main characteristics of this alloy are as follows:

309S stainless steel is austenitic chromium nickel stainless steel, which can withstand repeated heating below 980 ℃, with high temperature strength, oxidation resistance and carburizing resistance. Due to the high content of nickel (Ni) and chromium (CR), it has good oxidation resistance, corrosion resistance, acid alkali resistance and high temperature resistance

Microstructure of 309S

309S alloy is austenite matrix in solution heat treatment state.

The application fields of 309S include:

Widely used in boiler, energy (nuclear power, thermal power, fuel cell), industrial furnace, incinerator, heating furnace, chemical industry, petrochemical and other important fields

1. Furnace tube, furnace tank and mesh belt of heat treatment furnace

2. Shafts, structural parts and containers with temperature resistance below 980 ℃

3. Anchors and pins of refractories
