Factors affecting the polishing performance of stainless steel plates

Weldability: Different product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.

Corrosion resistance: Most stainless steel products require good corrosion resistance, such as Class I and II tableware, kitchen utensils, water heaters, water dispensers, etc. Some foreign merchants also do corrosion resistance tests on the products: use The NACL aqueous solution is heated to boiling. After a period of time, the solution is poured out, washed and dried, and the weight loss is weighed to determine the degree of corrosion. Rust spots appear)

Polishing performance (BQ property): At present, stainless steel products are generally polished during production, and only a few products such as water heaters and water dispenser liner do not need polishing. Therefore, this requires that the polishing performance of the raw material is very good. The main factors affecting the polishing performance are as follows: surface defects of raw materials.

Such as scratches, pitting, pickling, etc. Raw material problem. If the hardness is too low, it will not be easy to polish when polishing (the BQ property is not good), and if the hardness is too low, the surface is prone to orange peel during deep drawing, thus affecting the BQ property. BQ properties with high hardness are relatively good.
