Alloy Steel – Overview

Alloy steels are produced by combining carbon steel with one or more alloying elements such as manganese, silicon, nickel, titanium, copper, chromium, and aluminum. These elements are added in controlled proportions to achieve properties not attainable in standard carbon steel.

Key Performance Improvements

• Increased hardenability
• Improved corrosion resistance
• Retention of hardness and strength under service conditions
• Improved formability and toughness

Heat Treatment

Nearly all alloy steels require heat treatment to develop their intended mechanical properties and ensure consistent performance in demanding service environments.

Alloying Elements & Their Effects

• Chromium: Adds hardness, improves toughness and wear resistance
• Cobalt: Used in cutting tools; improves hot (red) hardness
• Manganese: Increases surface hardness; improves resistance to strain, hammering, and shock
• Molybdenum: Increases strength; improves resistance to heat and shock
• Nickel: Increases strength and toughness; improves corrosion resistance
• Tungsten: Improves grain structure, hardness, and heat resistance
• Vanadium: Increases strength, toughness, and shock resistance; improves corrosion resistance
• Chromium–Vanadium: Significantly improves tensile strength while remaining workable
