What influences polishing performance of stainless steel cross?

　　Stainless steel cross is a butt joint which changes the direction of pipeline in pipeline system. According to the production process can be divided into: casting cross, welding cross, stamping cross, push cross and so on.

　　The heat resistance of stainless steel cross is that stainless steel can maintain its excellent physical and mechanical properties at high temperature. Effect of Carbon: Carbon is strongly formed and stabilized in austenitic stainless steel. Elements that fix austenite and expand austenite zone. The ability of carbon to form austenite is about 30 times that of nickel. Carbon is a kind of interstitial element. The strength of austenitic stainless steel cross can be significantly increased by solution strengthening.

　　Corrosion resistance: When the number of chromium atoms in steel is not less than 12.5%, the electrode potential of steel can change abruptly from negative potential to positive potential. Prevent electrochemical corrosion.

　　Factors affecting polishing performance of ASTM A234 WPB 2 Inch Stainless Steel Cross:

　　1. Surface defects of raw materials. Such as scratches, pitting, acid washing, etc.

　　2. After deep stretching, small black spots will appear on the surface of the area with large deformation, thus affecting the stainless steel cross BQ property.

　　3. Material quality of raw materials. When the hardness is too low, polishing is not easy to shine, and the hardness is too low. The orange peel phenomenon is easy to appear on the surface when deep drawing, which affects the BQ property. BQ with high hardness is relatively good.
