201 Stainless steel vs 202 Stainless steel
1. 202 Stainless steel and 201 Stainless steel are two models with different materials. In fact, the biggest difference in composition lies in the difference in corrosion resistance. 200 series stainless steel belongs to low-nickel and high-manganese stainless steel. The nickel content is generally below 4%, and the manganese content is about 8%. It is a nickel-saving stainless steel.
2. 202 stainless steel is widely used in architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places. 202 stainless steel is formed by high-precision automatic pipe-making equipment through self-erosion welding, rolling and forming, and filling gas protection (inside and outside of the pipe) without any metal filler. The welding method is TIG technology, and online solid solution eddy current flaw detection.
3. 201 stainless steel has certain acid and alkali resistance, high density, no bubbles and no pinholes after polishing, and is a high-quality material for the production of various watch cases and strap bottom covers. 201 stainless steel is mainly used to make decorative pipes, industrial pipes, and some shallow stretched products.
4. In addition, manganese is commonly found in 201 and 202 stainless steel, and their use as a tableware material will cause harm to human health, and the country has explicitly banned it.
