1.Corrosion resistance
Most stainless-steel pipe products require good corrosion resistance. stainless-steel products like Class I and sophistication II tableware eg. kitchen utensils, water heaters, water dispensers, etc. a part of Chinese stainless-steel manufacturers will do corrosion resistance tests on the products: using NACL solution to take boiling, and therefore the problem solutions after a period of your time is to empty, wash and dry, from which to spot the load loss to substantiate the degree of corrosion.
2. Weldability
The welding performance requirements of chrome steel coils vary from product to product. a form of tableware usually doesn't require welding performance, even including some manufacturers of pots and pans. However, most products require raw materials with good welding performance, like Class II tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
3. Polishability
Currently, stainless-steel pipes are generally polished during the assembly, and only some products don't require polishing like water heaters, water dispenser linings, etc.. Therefore, this needs good polishing performance of the stuff. the most factors affecting polishing performance are as belows:
3.1. The surface defect of the material. like scratches, pitting, soaking, etc.
3.2. stainless-steel pipe material problem. If the hardness is simply too low, it's difficult to shine during polishing (BQ isn't good). If the hardness is simply too low, the surface is definitely to peel during deep drawing, which affects the BQ performance. BQ with higher hardness is comparatively better.
3.3. After deep drawing, small black spots and RI high imitating DGING also will appear on the surface of the realm with larger deformation, which is able to affect the BQ property.
