Alloy steel is a specialized form of steel that includes various alloying elements, such as chromium, nickel, molybdenum, and vanadium, in addition to carbon. These elements are introduced to enhance the steel's mechanical properties, including strength, toughness, hardness, and corrosion resistance. By adjusting the composition of these alloying elements, manufacturers can tailor alloy steel to meet specific performance requirements for a wide range of applications across various industries.

Commonly used in sectors such as automotive, aerospace, construction, oil and gas, and power generation, alloy steel is known for its versatility and durability. It can be classified into low-alloy and high-alloy steels, depending on the percentage of alloying elements present. This adaptability makes alloy steel ideal for applications that demand high performance, such as heavy machinery, structural components, and piping systems in extreme conditions.
