EN-24
EN-24 Alloy Steel
Application : Automobile Industry,
Construction, Pharmaceutical / Chemical Industry, Oil & Gas Industry
EN-24 is a through-hardening alloy steel which offers excellent machinability in the “T” condition. EN24T is used in components such as heavy duty shafts, gears, studs and bolts, its hardness is in the range 248-302 HB. EN24T can be further surface-hardened by induction or nitriding processes, producing components with enhanced wear resistance. EN24 steel is a readily machinable material, widely used as engineering steel due to its tensile strength. The material provides a combination of high tensile strength with shock resistance, ductility and wear resistance. EN24T also retains its good impact properties at low temperatures which means it if often used in harsh offshore environments.

Chemical Composition% :
Hardening :
Heat uniformly to 823/850°C until heated through. Quench in oil.Tempering: Heat uniformly and thoroughly at the selected tempering temperature, up to 660°C and hold at heat for two hours per inch of total thickness.Tempering between 250-375°C in not recommended as this can seriously reduce the steels impact value.
Stress Relieving :
Heat slowly to 650-670°C, soak well. Cool the EN24 tool in a furnace or in air.
Applications :
EN24 is often used to produce parts for heavy equipment such as locomotives, cranes, rolling mills and coal cutting machinery, gears, studs and bolts
