Alloy steels or high-tensile steels are low-carbon steel, or steels at the lower end of the medium-carbon range. Alloy steel has additional alloying ingredients in order to increase its strength, wear properties, or specifically tensile strength.
These alloying ingredients include chromium, molybdenum, silicon, manganese, nickel, and vanadium. Impurities such as phosphorus or sulfur have their maximum allowable content restricted.
Alloy steel ingredients provide a range of properties and compositions for a number of industries. These properties include increased hardness, corrosion resistance, and wear resistance; improved toughness and ductility; good weldability and tensile strength; and increased electrical and magnetic properties.
4140 Alloy Steel, due to these ingredients, is a versatile metal option for many applications. 4140 Alloy Steel can also be heat treated, tailored through heat treatment processes like quenching and tempering.
