Introduction
309 s corresponding Chinese brand is 0 cr23ni13, American standard S30908 (American AISI, ASTM) .corrosion resistance, heat resistance are better than 0 cr19ni9.309 s is containing sulfur free cutting stainless steel.

It is a variation of 309 stainless steel  with lower carbon content. It is applied to the occasion. Low carbon content is made in the heat affected zone near the weld in the precipitation of carbide to a minimum,which may result in precipitation of carbide stainless steel inter-granular corrosion in some environments (welding erosion)

Hot-rolled plate
1. Toughness and poor surface roughness, the price is low;
2. The temperature of hot rolling is similar to the forging temperature;
3. Hot plate with hot rolling surface oxide processing, thickness difference
4. Hot-rolled product prices and the use of relatively cold to a wide range of more;
5. Hot-rolled steel, mechanical properties far less than cold, but also inferior to forging processing, but have good toughness and ductility
6. The surface of the hot-rolled plate without plating is dark brown
7. From the plating can be distinguished from the degree of surface smoothness, hot rolled plate smoothness is low.

Application
309S Generally used for furnace material, produced in 850 ℃ -- 1050 ℃ work of all kinds of heat-resistant artifacts, such as bracket, conveyor belts,annealing furnace cover, thermal cracking tubes, etc. Mainly used for free cutting and the surface which is bright and high clean demanding occasions
