309 hot rolled stainless steel plate
309L is a variant of 309 stainless steel with a lower carbon content for applications where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may result in intergranular corrosion (weld erosion) in certain environments.

Simple description about 309s stainless steel
The 309S is a free-cutting stainless steel containing sulfur for applications where it is mainly required for easy cutting and high gloss.
Different between 309 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
It can withstand repeated heating below 980 °C, and has high high temperature strength, oxidation resistance and carburization resistance.
Applications: petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries
