Applications:
- 201 stainless steel pipe with acid and alkali resistance, high density, polishing without bubble, pinhole, etc., is producing all kinds of watch case, strap bottom cover high quality material, etc. It is mainly used for writing as a decorative tube, industrial pipe, some shallow tensile products.
- 304 stainless steel is widely used in food equipment, general chemical equipment, atomic energy industrial equipment parts, etc., are widely used. Suitable for deep drawing parts and acid pipeline, container, etc. Vehicles, auto parts boxes, home appliances are using this material. It is in the austenitic stainless steel production and consumption of steel, most used in the production of thin-walled, acid pipeline and parts, etc. Also often for chromium nickel stainless steel and stainless steel welding core material, non magnetic components and use components such as low temperature environment.
- 316 l stainless steel pipe is a hollow long round steel, mainly is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc. In addition, in the bending and torsional strength phase at the same time, the weight is lighter, it is widely used in the manufacture of machinery parts and engineering structures. Also commonly used for the production of various kinds of conventional weapons, barrel, shells, etc.
