Main Characteristics Of Stainless Steel

Aug 13, 2019

Main Characteristics of Stainless Steel:


1.Weldability

Different products have different requirements for welding performance.Most products require good welding performance of raw materials, such as second-class tableware, vacuum flasks, steel pipes, water heaters, water dispensers, etc.

 

2.Corrosion resistance

Most stainless steel products require good corrosion resistance, such as Class I and Class II tableware, kitchen utensils, water heaters, water dispensers, etc. Some foreign businessmen also do corrosion resistance test on products: use NACL aqueous solution to warm to boiling, after a period of time Drop the solution, wash and dry, weigh the weight loss, to determine the degree of corrosion.


3.Polishing performance

Stainless steel products are generally polished during the production process. The main factors affecting the polishing performance are as follows:

A. raw material surface defects. Such as scratches, pitting, soaking and so on.

B. raw material problems. The hardness is too low, it is not easy to be polished when polishing (BQ is not good), and the hardness is too low, and the surface is prone to orange peel phenomenon during deep drawing, thereby affecting BQ property. The BQ with high hardness is relatively good.

C. After deep drawing, the surface of the area with a large deformation will also have small black spots and RIDGING, thus affecting BQ.

 

4.Heat resistance

Heat resistance means that stainless steel can maintain its excellent physical and mechanical properties at high temperatures.


5.Corrosion resistance

When the amount of chromium in the steel is not less than 12.5%, the electrode potential of the steel is abruptly changed from a negative potential to a positive electrode potential. Prevent electrochemical corrosion.
