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)

Cold-rolled plate
1. Stretch good, toughness, but the price is more expensive;
2. Cold rolling processing surface without oxide skin, good quality;
3. Cold rolling is generally used in the production of strip, the rolling speed is high;
4. Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;
5. Cold-rolled steel plate due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;
6. Cold plate yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents
7. The surface of the cold rolling plate without plating is gray.
8. Cold rolling plate plating surface smoothness is higher than the hot plate.

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
