What is Alloy Steel?
Alloy steel is steel in which additional alloying elements such as chromium, nickel, molybdenum, manganese, silicon and vanadium are added to improve specific mechanical or physical properties.
Compared with ordinary carbon steel, properly selected alloy steels can provide improved strength, toughness, hardenability, wear resistance and performance at demanding operating conditions.
The final properties depend on the chemical composition, manufacturing process, heat treatment and applicable specification.
