Grades & Standards Steel Grades Alloy Steel
Alloy Steel
Alloy steel delivers a combination of strength, toughness, and wear resistance that standard carbon steels can’t match. By adding elements such as chromium, nickel, molybdenum, or vanadium, these steels achieve improved hardenability, corrosion resistance, and performance under heat or stress. At Steel Warehouse, we process and supply alloy steels that meet precise mechanical and dimensional requirements for structural, wear, and high-performance applications. With decades of metallurgical expertise and advanced processing capabilities, we help customers choose and process the right alloy grade to match performance goals and production demands.
Effects Of Alloying Elements
Element
Positives
Negatives
Carbon (C)
Increases strength and hardness
Manganese (Mn)
Increases strength and hardness. Mitigates Sulfur (S).
Phosphorus (P)
Increases strength and hardness. Reduces corrosion.
Decreases ductility and toughness. Segregates.
Sulfur (S)
Decreases ductility and toughness. Reduces weldability.
Silicon (Si)
Aluminum (Al)
Added to “tie-up” Oxygen. Smaller grain size to increase strength and toughness
Vanadium (V)
Niobium (Cb, Nb)
Chromium (Cr)
Increases strength. Slows corrosion
Copper (Cu)
Slows corrosion
Nitrogen (N)
Increases strength and hardness
Boron (B)
Molybdenum (Mo)
Increases strength
