What are Stainless Steel Flanges?

Stainless Steel Flanges are built from various stainless steel materials. Stainless steel grades differ depending on the material composition, and mechanical properties vary. The great corrosion resistance of stainless steel flange is due to the elements of Chromium, and as Cr increases, better resistant performances will be gained.

Molybdenum additions, on the other hand, improve corrosion resistance in reducing acids and resistance to pitting attack in chloride solutions. As a result, different grades of stainless steel with varying Cr and Mo compositions are available to suit the environment in which they must be alloyed.
