309/309S stainless steel
309S is cutting stainless steel containing sulfur, the main requirements for cutting and surface finish high occasions. Widely used in important areas boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, furnaces, chemical, petrochemical, and other.
The only difference is that 309 stainless steel does not contain sulfur, and now basically produce steel 309S material. Both can be summed up as the same material.,have the same purpose.To some extent, the carbon content of 309S is lower than 309.

Applications
Widely used for easy cutting and high surface finish.with corrosion resistance, excellent high temperature performance, it can withstand 980 C high temperature.So it is widely used in energy (nuclear power, thermal power, fuel cell), industrial furnace, heating furnace, incinerator, chemical, petrochemical and other fields.
321 stainless steel plate
About 321 stainless steel
321 stainless steel belongs to austenitic stainless steel, its performance is very similar to the 304, but due to the addition of the metal titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium, making it effective control of the formation of chromium carbide.
Excellent high-temperature stress of 321 stainless steel with a breaking (Stress Rupture) properties and high temperature creep resistance (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.

310/310S stainless steel plate
310/310S stainless steel
310 stainless steel austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because the higher percentage of chromium and nickel, 310 has much better creep strength, can continuously work under high temperature, good heat resistance.
310S stainless steel is austenitic chromium nickel stainless steel, has a good 310S stainless steel oxidation resistance, resistance Corrosive.
Because of the high percentage of chromium and nickel, which has a much better creep strength, can continue to work at high temperature, with good heat resistance.
Due to the high content of nickel (Ni), chromium (Cr), good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, high temperature resistant steel pipe is used in the manufacture of electric furnace tubes and other occasions.
The only differences for 310 310S stainless steel is the 310 stainless steel does not contain sulfur elements.What’s more,the carbon content of 310S is much lower than 310.
