X2CrNiMo18-14-3、1.4435、X2CrNiMoN1812

Features and applications:
X2CrNiMo18-14-3 is to add N to X5CrNiMo17-12-2 steel, which improves the strength, but does not reduce the plasticity, so that the thickness of the material is reduced. X2CrNiMo18-14-3 has good corrosion resistance, heat resistance and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon; containing molybdenum and low carbon content, resistance in marine and chemical industrial environments The pitting corrosion ability is better than X5CrNiMo17-12-2 stainless steel.

X2CrNiMo18-14-3 is mainly used as a high-strength component with good corrosion resistance. Such as equipment used in seawater, chemicals, dyes, papermaking, oxalic acid, fertilizers and other production equipment as well as photographs, food industry, coastal area facilities, ropes, CD rods, bolts, nuts, etc
