What are the three major characteristics of stainless steel products?
Aug 04, 2021

One, corrosion resistance.
Most stainless steel products must have excellent corrosion resistance. Seamless steel pipes are similar to class I, II tableware, kitchen supplies, electric water heaters, water dispensers, etc. Some foreign-funded enterprises have also carried out corrosion resistance experiments on commodities: heated to boil with NACL solution, and after a period of time, the solution is to drain, clean, dry, measure the net weight damage, and determine the erosion level.
The second is the welding method.
Requirements for weldability vary from commodity to commodity. Tableware is generally not required to have weldability and is even included by some bottling companies. But the vast majority of commodities stipulate raw materials have excellent electric welding welding performance, such as the second type of tableware, thermal insulation cup, seamless steel pipe, electric water heater, water dispenser.

Three, polishing performance
Today, stainless steel products in the production process is generally after polishing, only a very few commodities such as electric water heater, water dispenser need not polishing. This stipulates that the raw material has excellent polishing properties. There are several key factors:
1. Surface defects of raw materials. Such as scratches, black spots, preleaching, etc.
2, seamless steel tube raw material problem. If the strength is too low, it is not easy to polish and polish when grinding and polishing (BQ is not good). If the strength is too low, the surface is prone to orange peel condition when deep drawing, which will harm the BQ performance. BQ has high strength and excellent performance.
3. After deep drawing, black spots will continue to occur on the surface of the heavily deformed area. RI fine DGING will cause harm to BQ features.
