Description
Alloy steel
When other elements comprising metals and non-metals are added to carbon steel, alloy steel is formed. These alloy steels display various environmental, chemical and physical properties that can vary with the elements used to alloy. Here the proportion of alloying elements can provide different mechanical properties.
Alloying elements
There are around 20 alloying elements that can be added to carbon steel to produce various grades of alloy steel. These provide different types of properties. Some of the elements used and their effects include:

Aluminium - can rid steel of phosphorous, sulfur and oxygen
Chromium - can increase toughness, hardness and wear resistance
Copper - can increase corrosion resistance and harness
Manganese - can increase high-temperature strength, wear resistance, ductility and hardenability
Nickel - can increase corrosion, oxidation resistance and strength
Silicon- can increase magnetism and strength
Tungsten - can increase strength and hardness
Vanadium - can increase corrosion, shock resistance, strength and toughness

Alloy steel products and their applications
There are hundreds of products that can be manufactured with alloy steels of varying compositions. These include alloy steel pipes and tubes, alloy steel plates, sheets and coils, alloy steel bars, rods and wires, alloy steel forged fittings, alloy steel buttweld fittings, alloy steel flanges, fasteners and more. Alloy steels have many uses in various industries such as automobiles, mining, machinery and equipment, railways, roadconstruction, buildings, appliances and off-shore applications.

Applications in building large structures
In the building and construction industry, alloy steels are used for very large modern structures such as airports, bridges, skyscrapers and stadiums in the form of a steel skeleton. Alloy steels provide the required high strength to support such large structures. Even concrete structures use alloy steels as reinforcement to add strength and reduce the overall weight of structures. Smaller items such as screws, nails and bolts made of alloy steels are used in the building and construction industry.

Applications in building bridges
Bridges use special alloy steels known as weathering steels. These provide enhanced protection from corrosion because of the presence of nickel, copper and chromium as alloying elements. Weathering steels also find uses in buildings as facing material to improve aesthetics. Weathering steel offers several benefits which include high safety, ease and quickness of construction, aesthetic looks, shallow depth of construction, low maintenance and amenable to alterations in the future. Because of its natural weathered finish, no painting is required thus avoiding environmental issues caused by paints. Weathering steels are extremely cost-effective in the long run.
