Metal Alloy With Enhanced Properties

Alloy Steel Plates


It’s a metal alloy which majorly consists of iron with addition of small amounts of carbon, depending on the grade & quality of the steel.

Alloy steel can be any type of steel to which one or more elements are added deliberately besides carbon, to produce a desired characteristic.The most common elements which are added in making of alloy steel are molybdenum, nickel, silicon manganese, chromium, boron, titanium, tungsten and vanadium.

The subdivisions of Alloy steels are High & low alloy steels. Usually alloy steel is considered as Low alloy steel.

Alloy steels have many enhanced properties than carbon steels which include corrosion resistance, strength, toughness, hardness, wear resistance and hot hardness.

The most commonly used grades of Alloy is Chromium Molybdenum Steel
Grade 4140(ASTMA387)

The addition of chrome & molybdenum increases the temperature tensile strength which makes it an highly suitable for elevated temperature environments. It also provides excellent corrosion resistance. ASTM A387 is ideal for the fabrication of weldable steel pressure vessels and industrial boilers which are found commonly in oil & petrochemical industries.

We hold a wide range of ASTM A387 Class 2 plates, which are readily available for supply & export.


Some of these alloy steels are being used in following special and high-demand applications like:
Turbine blades of jet engines
Nuclear reactors

With ferromagnetic properties of iron, some alloys steels also find important applications where their response to magnetism is required such as electric motors & transformers.
