Types of Alloy Steel
Alloy steels are steels that are alloyed with a variety of elements to improve their mechanical properties, corrosion resistance, wear resistance, and toughness.
| Category | Description | Common Alloying Elements | Applications |
|---|---|---|---|
| Low-Alloy Steel | Contains <8% alloying elements. Offers improved strength, toughness, and hardenability over carbon steel. | Chromium (Cr), Nickel (Ni), Molybdenum (Mo), Vanadium (V), Manganese (Mn) | Structural components, automotive parts, pipelines |
| High-Alloy Steel | Contains >8% alloying elements. Most common example is stainless steel. Offers excellent corrosion and heat resistance. | High Chromium (>10.5%), Nickel, Silicon, Tungsten | Aerospace, chemical processing, medical instruments |
| Stainless Steel | A corrosion-resistant steel containing ≥10.5% chromium. Often considered a subset of high-alloy steels. | Chromium, Nickel, Molybdenum | Food processing, medical tools, marine applications |
| Tool Steel | Special-purpose alloy steel designed for tool making and high hardness. Excellent wear and heat resistance. | Tungsten (W), Molybdenum, Vanadium, Cobalt (Co), Chromium | Cutting tools, dies, molds, punches |
| Spring Steel | A special low-alloy/high-carbon steel with high yield strength and elasticity. | Silicon, Manganese | Springs, automotive suspension, knives |
| Maraging Steel | Ultra-high strength steel alloyed with nickel and hardened by aging. Very tough and weldable. | Nickel (17–19%), Cobalt, Molybdenum, Titanium | Aerospace, tooling, rocket motor cases |
| Chromoly Steel | A type of low-alloy steel with chromium and molybdenum. Known for strength, toughness, and fatigue resistance. | Chromium, Molybdenum | Bicycle frames, roll cages, aircraft tubing |
