Alloy structural steel
Overview
Alloy structural steel is a type of steel formed by adding different proportions of alloy elements such as manganese, chromium, nickel, molybdenum, and vanadium. Its addition is to improve the mechanical and physical properties inside ordinary carbon steel, such as hardenability, tensile strength, yield ratio, fatigue strength, ductility, and corrosion resistance, making these types of steel suitable for manufacturing various mechanical parts with larger cross-sectional dimensions.
Product characteristics
Different yield strength, tensile strength, resilience, and plasticity.
After special heat treatment, excellent physical or mechanical properties can be obtained
Widely used in the manufacturing of various mechanical parts such as ships, vehicles, aircraft, missiles, weapons, railways, bridges, pressure vessels, machine tools, etc.
