Alloy Steel Wire / Rod
Alloy steel wire refers to steel wire made from alloy steel rods that are combined with elements such as chromium (Cr), molybdenum (Mo), nickel (Ni), silicon (Si), or vanadium (V) to enhance specific properties like strength, toughness, hardness, wear resistance, and heat resistance. These alloying elements significantly improve the wire’s mechanical and chemical performance, especially under high load, high temperature, or corrosive environments.
Alloy steel wires are widely used in automotive components, heavy machinery, springs, oil & gas equipment, aerospace parts, and other industrial applications that demand superior performance.
