In metallurgy, stainless steel also called as inox steel or inoxidizable steel. It is a steel material alloyed with high content of chromium and nickel, where
Minimum Cr at 10.5%
Minimum Ni at 8%
Maximum Carbon at 1.5%
As we know, stainless steel flange is impressed by it's great corrosion resistance, which because of the elements of Chromium, and as Cr increased, better resistant performances will be gained.
On the other hand, additions of Molybdenum will increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. So there are different grades of stainless steel with varying Cr and Mo compositions to suit the environment with required to be alloyed.

Many different types of stainless steel flanges can be incorporated into a piping system. Stainless steel flanges are highly resistant to rust, are much stronger and can out perform carbon steel flanges and provide much more corrosion resistance than your aluminum or steel flanges.
ASME (American Society of Mechanical Engineers) flanges are engineered to meet certain standards. These standards are specified by the ASME and by the American National Standards Institute (ANSI). There are certain specifications in all flanges, each depending on the certain type of flange. This similarity ensures consistency with the same types of flanges used and replaced now and in the future.
