Alloy Steel Manufacturer
Omsteel is a manufacturer of high-quality alloy steel products. Alloy steel is a type of steel that contains other elements besides carbon, such as chromium, nickel, molybdenum, vanadium, and/or manganese. The addition of these alloying elements gives the steel improved strength, toughness, corrosion resistance, and other desirable properties.
Alloy steel has a wide range of applications due to its improved properties. It is commonly used in industries such as aerospace, automotive, construction, energy, and manufacturing. Omsteel uses advanced manufacturing processes and quality control measures to ensure that alloy steel products meet the highest standards of quality and performance. We have a team of experienced engineers and technicians who work closely with customers to provide tailored solutions for their specific requirements.
Properties of Alloy steel
Strength
Corrosion resistance
Alloy steel has better corrosion resistance compared to carbon steel due to the presence of alloying elements like chromium and nickel. These elements form a protective layer on the surface of the steel, preventing it from rusting or corroding.
Weldability
Duplex steel is generally considered to be highly weldable, although care must be taken to avoid certain welding defects that can occur.
