Overview of Alloy Structural Steel

Alloy structural steel are the type of steels formed by adding different proportions of alloying elements like manganese, chromium, nickel, molybdenum, vanadium, the addition of which is to enhance the mechanical and physical properties within the ordinary carbon steel, such as hardenability, tensile strength, yield ratio, fatigue strength, ductility, and corrosion resistance, which allows these type of steels suitable for manufacturing various machine parts with larger cross-sectional dimensions.

Features of Alloy Structural Steel

  • 1

    Varying yield strength, tensile strength, resistance to tempering, and plasticity.

  • 2

    Excellent physical or mechanical properties are obtained after specific heat treatment

  • 3

    Widely used for manufacturing various machine parts in ships, vehicles, aircraft, missiles, weapons, railways, bridges, pressure vessels, machine tools, etc.
