It can be widely used in petrochemical, electric power, nuclear industry, medicine, food and other industries.
Use editing
Industrial stainless steel coils: heat exchangers, boilers, petroleum, chemicals, fertilizers, chemical fiber, pharmaceuticals, nuclear power, etc.
Stainless steel coils for fluids: beverages, beer, milk, water systems, medical equipment, etc.
Stainless steel coils for mechanical structures: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automotive and marine accessories, construction and decoration, etc.
Stainless steel bright coil: welded by stainless steel strip and then reduced wall, reducing the thickness from thin to thin, this process can make the wall thickness uniform and smooth, and the wall of the reduced wall has a weld-free effect. According to the naked eye, it is a seamless tube, but the process is determined to be a welded pipe. The process of reducing the wall is accompanied by bright annealing, so that the inner and outer walls do not form an oxide layer, and the inside and outside are bright and beautiful, which is really required for medical products. The next process needs to be sizing, that is, the small pull process, determine the outer diameter, the outer diameter tolerance can generally reach plus or minus 0.01mm.

Austenitic stainless steel is stainless steel with austenitic structure at high temperature and normal temperature.
The steel contains about Cr of about 18%, Ni 8%~10% and C about 0.1%, and has stable austenite structure.
Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel
and the high Cr-Ni series steel which is developed on this basis by adding Cr, Ni content and adding Mo, Cu, Si,
Nb, Ti and other elements.
Austenitic stainless steel is non magnetic and has high toughness and plasticity, but its strength is low.
It is impossible to strengthen it by phase change. It can only be strengthened through cold processing,
such as adding S, Ca, Se, Te and other elements. It has good cutting ability.
