X2CrNiMo17-13-2、X2CrNiMo17 12、X2CrNiMo17 13

characteristic:
X2CrNiMo17-13-2 stainless steel has good plasticity, toughness, cold deformation, good welding process performance, X5CrNiMo17-13-3 high temperature strength is good, X2CrNiMo17-13-2 high temperature performance is slightly worse, but the corrosion resistance is better than X5CrNiMo17-13-3, because Low carbon content and containing 2℅ ~ 3℅ molybdenum improves the corrosion resistance of reducing salts and various inorganic and organic acids, alkalis, salts, and high-temperature strength.

X2CrNiMo17-13-2 stainless steel is an acid-resistant and anti-corrosion alloy material, which is divided into two series of nickel stainless and chromium stainless. It has many unique excellent properties such as high temperature resistance, easy processing, high strength and so on. Products are widely used in many fields of industry and civilian use.
