DAMASCUS Three-ply composite steels is a special type of steel, also known as low-alloy high-strength structural steel, which refers to
high-strength alloy structural steel containing chromium, molybdenum, and steel elements
The materials are of 304 stainless steel+316 stainless steel with steel core 10Cr15MoVCo or 9Cr18MoV as customer’s request
It has been widely used due to its excellent properties such as high strength, wear resistance, and corrosion resistance.
It is widely used in various fields, including construction, aerospace, trains, power equipment, automobiles, medical equipment,
metallurgy, chemical engineering, and marine engineering etc.
