What Is 309 Stainless Steel Plate?
309H, 309S, and 309 stainless steel plates are chromium-nickel austenitic stainless steel grades, which are often used in high-temperature environments. Due to their high chromium and nickel content, these grades of stainless steel plates have a high degree of corrosion resistance, excellent oxidation resistance, and excellent heat resistance. This type of stainless steel also has excellent strength at room temperature and high temperatures. The main difference between 309 and 309S stainless steel is the carbon content. 309S contains less carbon, which minimizes carbide precipitation and improves weldability. 309H and 309 plates are also different in carbon content. 309H stainless steel plate contains more carbon than 309 stainless steel, which leads to increased creep resistance.

Different between 309 Stainless Steel Plate and 309s
309 stainless steel. 309S stainless steel – S30908 (American AISI, ASTM) 309S. The steel mill produces more 309S stainless steel, which is better in corrosion resistance and high-temperature resistance. Can withstand 980 °C high temperature. Mainly used in boilers, chemicals, and other industries. 309 does not contain sulfur S content compared to 309S
Simple Features about 309 stainless steel Plate
- It can withstand repeated heating below 980°C and has high-temperature strength, oxidation resistance, and carburization resistance.
- Corrosion resistance: 309 stainless steel can stand well in various atmospheric environments even when exposed to corrosive elements.
- Heat resistance: It can be hot processed at 1177⁰C and then quenched quickly.
- It is easy to weld using fusion welding or resistance welding (but it is better not to use oxyacetylene).
- Even if the work hardening rate is high, punching, upsetting, drawing, and stamping can be performed.
Applications: petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military, and other industries.
