321 Stainless Steel Plate

321 Stainless Steel Plate

321 stainless steel plate/sheet is a stainless steel plate with high strength, high temperature stability and corrosion resistance. It is obtained by high temperature treatment of 304 stainless steel with titanium added, which also makes 321 stainless steel plate have better mechanical properties and high temperature resistance than 304 stainless steel.

🔵 Description:

 

 

321 stainless steel plate/sheet is a stainless steel plate with high strength, high temperature stability and corrosion resistance. It is obtained by high temperature treatment of 304 stainless steel with titanium added, which also makes 321 stainless steel plate have better mechanical properties and high temperature resistance than 304 stainless steel.

 

The corrosion resistance of 321 stainless steel plate is similar to that of 304 stainless steel, and it can obtain good corrosion resistance in various acid, alkali and salt environments. This is because the titanium added to 321 stainless steel can form a titanium layer to protect the stainless steel surface from corrosion.
