Alloy steel plate

    Alloy Steel Plates is steel this is alloyed with a different elements in overall quantities among 1.0% and 50% by weight to enhance its mechanical properties. Alloy steels have to type which is low-alloy steels and high-alloy steels. The difference between the two is relatively arbitrary.

    As plates, these include strength, hardness, toughness, wear resistance and corrosion resistance. Many of the alloy steels are easy to machine, stamp and fabricate and can be manufactured to precise tolerances.

    Alloy steel plates are defined as steel plates with a definite range or definite minimum quantity of additional elements, depending on the alloy.

Principal effects of alloying elements for steel

ElementPercentagePrimary function
Aluminium0.95–1.30Alloying element in nitriding steels
BismuthImproves machinability
Boron0.001–0.003(Boron steel) A powerful hardenability agent
Chromium0.5–2Increases hardenability
4–18Increases corrosion resistance
Copper0.1–0.4Corrosion resistance
LeadImproved machinability
Manganese0.25–0.40Combines with sulfur and with phosphorus to reduce the brittleness. Also helps to remove excess oxygen from molten steel.
>1Increases hardenability by lowering transformation points and causing transformations to be sluggish
Molybdenum0.2–5Stable carbides; inhibits grain growth. Increases the toughness of steel, thus making molybdenum a very valuable alloy metal for making the cutting parts of machine tools and also the turbine blades of turbojet engines. Also used in rocket motors.
12–20Increases corrosion resistance
Silicon0.2–0.7Increases strength
2.0Spring steels
Higher percentagesImproves magnetic properties
Sulfur0.08–0.15Free-machining properties
TitaniumFixes carbon in inert particles; reduces martensitic hardness in chromium steels
TungstenAlso increases the melting point.
Vanadium0.15Stable carbides; increases strength while retaining ductility; promotes fine grain structure. Increases the toughness at high temperatures

Application of alloy steel plate

    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, road construction, 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.

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.
