Virat Special Steels is the biggest & leading Supplier & Stockiest of EN24 in India.
EN24steel is high tensile alloy steel famed for its wear resistance properties and in addition where high strength properties are required.
This Grade is used in components akin to gears, shafts, studs and bolts, its hardness is within the range 248/302 HB. It may be further surface-hardened to create add-ons with more advantageous wear resistance by means of induction or nitriding processing.
Standard hiqh-speed steel qrade. Itswell-balanced alloy composition forms the basis of its high_touqhn-essand good clllting edge retention, rendenng it $uitable for a large variety of appllcatons.
