Specifications

301 Stainless Steel Strip

Good extension ability, used for mould products. It can also be hardened at machine speed. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel strip.

304 Stainless Steel Strip

304 grade is a common material in stainless steel area, with a density of 7.93 g/cm³, which is also called 18/8 stainless steel in the industry. GB standard is 0Cr18Ni9.

304 stainless steel strip has good weldability. These strips products can be used for vessel parts, stainless steel welding pipes, stainless steel flexible hose and corrugated pipe, etc.

304L Stainless Steel Strip

It is a variant of 304 stainless steel with lower carbon content, used in occasions where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause stainless steel to produce intergranular corrosion (welding erosion) in certain environments.

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.
