An alloy steel is a type of steel combined with more than one element (alloying elements). Alloying elements increase strength, hardness, wear resistance, and toughness, producing more robust and substantive steel. The alloying elements added to the base iron and carbon structure typically total no more than 5% of the alloy steel’s material composition.
Steel Alloy AdvantagesWhether your project requires advanced corrosion resistance, machinability, strength, or a bevy of other qualities, there is an alloy steel that provides the features you need. With added heat treatment, alloy steels can offer a wide range of beneficial attributes, including:
- Enhanced corrosion resistance
- Increased hardenability
- Superior strength and hardness
- Unique alloyed features
Steel Alloy Manufacturing ProcessesSteel alloys are traditionally manufactured by combining percentages of pure elements until the proper chemical makeup is achieved. Adequate mixing is easily accomplished within liquid states but extremely slow and challenging in solid forms. The components are purified in the liquid state, mixing the alloying agents with the base metals.
High & Low Steel Alloy Differentiating QualitiesHigh alloy steel has alloying elements (not including carbon or iron) that make up more than 8% of its composition. These alloys are less common because most steel only dedicates a few percent to the additional elements. Stainless steel is the most popular high alloy, with at least 10.5% chromium by mass. This ratio gives stainless steel more corrosion resistance. The chromium oxide coating acts as a sacrificial layer that slows down rusting of the substrate material.
Low alloy steel is only modified slightly with other elements, which provides slight advantages in hardenability, strength, and free machining. By lowering the carbon content to around 0.2%, the low alloy steel will retain its strength and boast improved formability.
Common Steel Alloying ElementsWhen it comes to steel, many elements can be added to the base material, allowing the purchaser to tweak variances until the proper alloy is found. Common alloying elements include the following:
- Manganese: Used in tandem with small amounts of sulfur and phosphorus, the steel alloy becomes less brittle and easier to hammer.
- Chromium: A small percentage (0.5% - 2%) can help to harden the alloy; more significant percentages (4% - 18%) have the added effect of preventing corrosion.
- Vanadium: With only .15%, this element can boost strength, heat resistance, and overall grain structure. Mixed with chromium, the steel alloy becomes much harder but retains its formability.
- Nickel: Up to 5%, this alloying element will improve the steel’s strength. In excess of 12%, it provides impressive corrosion resistance.
- Tungsten: Boosts heat resistance, so the melting point is higher. It also improves the structural makeup of the steel.
Typical Steel Alloy ApplicationsSteel alloys can be forged into various shapes, including pipes, tubes, plates, sheets, coils, bars, rods, wires, forged fittings, buttweld fittings, flanges, fasteners, and more. Steel alloy industrial applications include the following:
- Road construction
- Offshore duties
