ALLOY STEEL
Delivering trusted steel solutions with unmatched quality and service across India.
Description
Alloy steel refers to steel that can be fabricated almost flexibly by transforming iron into an alloy with manganese, chromium, nickel, molybdenum, vanadium, silicon, or boron. From such alloying, considerable improvement occurs in the strength, hardness, toughness, wear resistance, and corrosion resistance character of the steel, enabling the use of the material in demanding industrial applications.
Based on alloying proportions from 1% up to 50%, alloy steels can be classified into two categories:
- Low Alloy Steel – low alloy steel normally has up to 5% of alloying elements and gives an excellent balance of strength versus cost.
- High Alloy Steel – these steels have more than 5% alloying elements and are designed for better performance under extreme conditions.
In sectors such as oil and gas, automotive, manufacturing, and engineering, low-alloy steel is often equated to alloy steel due to its toughness and excellent performance under critical operations.

Conclusion
Alloy steels are a specific combination of compositions and mechanical properties, thus having a vast range of uses in modern engineering and industry. They provide an economically viable answer in tough, economically low-alloy steels, to a high-alloy steel offering an ultra-high performance, and are the mainstay of automotive, oil and gas, aerospace, and power generation industries.
Grades like EN31, EN24, EN353, etc. can be used for various applications requiring excellent wear resistance, high tensile strength, and exceptional toughness under tensile loading conditions. Alloy steels remain invaluable in the industries because of their versatility in their designs, the ability to undergo thermal treatment processes, and applicability in the most important industries in the world.
