Specifications

321 And 347 Stainless Steel Strips

These grades stainless steel stabilized with titanium, niobium plus tantalum, and niobium respectively. They are suitable for welding components used at high temperatures.

321 austenitic stainless steel strip has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries.

347 stainless steel strip is one of stabilized stainless steel strips which offers as its main feature an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation up to 800 degree.

316L And 317L Stainless Steel Strips

Contains aluminum, so the resistance to pitting corrosion in marine and chemical industrial environments is much better than 304 stainless steel.

316L stainless steel strip is almost identical to 316 grade strip.

316L stainless steel strip has lower carbon content imparts even better corrosion resistance than 316.

309S And 310S Stainless Steel Strips

Nickel and chromium content are relatively high, in order to improve the oxidation resistance and creep strength of steel at high temperatures.

309S stainless steel strip has high chromium and low nickel content, It can be utilized in sulfur containing atmospheres up to 1000 degree.

310S stainless steel strip is austenitic chromium-nickel stainless steel with good oxidation resistance and resistance, corrosion and high temperature resistance.
