1, corrosion resistance   

Most stainless steel products require good corrosion resistance.  Stainless steel pipes similar to class I and II cutlery, kitchen appliances, water heaters, water dispensers, etc.  Some foreign merchants also test the product for corrosion resistance: use NACL aqueous solution to warm to boiling, after a period of time the solution is to drain, wash and dry, determine weight loss to determine the degree of corrosion.
 
 2. Welding machinability  

Welding performance requirements vary from product to product.  A tableware usually does not require welding properties, even for some pot enterprises.  However, most products require raw materials with good welding performance, such as class II tableware, thermos cups, steel pipes, water heaters, drinking machines and so on.
 
 3, polishing  

At present, stainless steel products are generally polished in the production process, only a few products such as water heaters, water dispensers lining do not need to be polished.  Therefore, this requires good polishing properties of the raw material.   

The polishing performance is affected for the following three reasons:
 
 (1) There are problems on the surface of raw materials: scratches, damage, immersion, etc.;   (2) Stainless steel pipe raw material hardness is low, BQ is not good, deep drawing is prone to orange peel phenomenon, affecting the BQ performance of continuous square steel pipe, high hardness will be better.   (3) Black spots may appear on the surface of the stainless steel tube after deep drawing, which affects the BQ attribute of the stainless steel tube.
