About Stainless Steel 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. Advantages: Resistant to corrosion and staining Low maintenance Bright familiar luster Steel Strength
