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.

Cold rolled | 0.8mm-3.0mm | Standard width in China:1000mm 1219mm 1500mm Special width:can be ordered | 2B / No.4 / HL / BA / Mirror etc | TISCO / ZPSS etc |
Hot rolled | 3.0mm-80.0mm | Standard width in China:1219mm 1500mm 2000mm Special width:can be ordered | No.1 | TISCO / ZPSS etc |
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 coil
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.
Stainless Steel Strip
Stainless steel strip is simply an extension of an ultra thin stainless steel plate. A narrow and long steel plate produced mainly in order to meet the needs of industrial production of various metals or mechanical products in different industrial sectors.Actually,stainless steel is produced by stainless steel coil.Usually use the slitting machine to process it into strip,with the same usage with stainless steel coil.
304/304Lstainless steel coil
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.
