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.

Applications
310 310S stainless steel is the most common choice of boiler materials. Also widely used in stamping dies, fixtures, tools, gauges, paper cutting knives, tools, petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries!
About 201 /202 stainless steel
201 stainless steel is the most widely used in the 200 series. Because 201 stainless steel With"acid"and "alkali resistance"and"high density", "no bubbles", "no pinhole, polishing".
201 is the choice of all kinds of "watchcase", "watchband bottom”,"decorative tubes", "industrial tubes", and a plurality of products with shallow drawing etc.
Compared with 201 grade,the only difference with 201 is that the Nickle contenting,and with the same applications,characteristic etc.
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.
