309 Stainless Steel Rod

309S Stainless steel--s30908 (USA AISI, ASTM) 309S. Steel production is more than 309S stainless steel, corrosion resistance, high temperature performance is better. Can withstand 980°C high temperature.

Mainly used in boilers, chemical industry and other industries. 309 compared with 309S, it does not contain sulfur s content.

309 Stainless steel plate is now rarely sold, mainly 309S stainless steel rods, if you want to find 309 steel rods, it is recommended that you choose more durable and better quality 309 stainless steel Rods.

309S is a sulphur-containing easy-cutting stainless steel, for the main requirements of easy cutting and high surface finish of the occasion.

309s is a variant of 309 stainless steel with low carbon content, used for welding occasions. The lower carbon content minimizes the amount of carbide precipitated in the heat-affected zone near the weld, and the precipitation of carbides may lead to intergranular corrosion in some environments (weld erosion).
