What is CG8M Stainless Steel ?
CG8M alloy is a kind of austenitic steel alloy containing molybdenum. Compared with ordinary stainless steel, it has better chemical resistance. In addition,
This stainless steel has high fracture stress strength and excellent ductility at high temperature.
Because of its good chemical resistance, this stainless steel is often used in the manufacture of synthetic fibers, petrochemical industry, textile and papermaking.

317 stainless steel
317 stainless steel is a kind of high alloy steel which can resist corrosion in air or chemical corrosive medium. This kind of stainless steel has beautiful surface and good corrosion resistance. It can give full play to the inherent surface properties of stainless steel without surface treatment such as plating color. 317 stainless steel is a kind of steel alloy used in many fields
