Description
Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
The properties of stainless steel are corrosion resistance, high ductility, attractive appearance and low maintenance.
Application
The surface brightness and flatness of 2B is better than 2D then theough a special surface treatment to improve its mechanical properties,2B could nearly Satisfy comprehensive uses
- Be extensively applied to architectural decoration, such as elevator decoration, luxurious doors, outdoor projects, wall decoration, advertisement nameplates, sanitary ware, ceiling, corridor, hotel hall, shop facade, etc.
- For furniture, kitchenware, food industry, electronic industry, medical equipment, etc.
Classification
stainless steel coil is widely used in construction, surgery, kitchen essentials, etc. 304 stainless steel is suitable for the construction of external banisters and handrails, and it has good processing performance and weldability. 316 stainless steel is suitable for kitchen essentials such as equipment, cutlery and cookware, and it has good corrosion resistance and a wide range of shapes. 316L stainless steel is suitable for medical and surgical applications, which demand high levels of reliable performance.
