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.

.35-.45 .45 - .70 .10-.35 0.04 0.04 .90-1.40 1.30-1.80 .20-.40

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

  • EN-9
  • EN-19
  • EN24
  • EN31
  • EN-41B
    • Each grade is designed for specific industrial applications and performance requirements.

EN19 alloy steel is widely used for gears, shafts, bolts, axles, and heavy-duty machinery components because of its high tensile strength and toughness.

EN24 offers higher tensile strength and better fatigue resistance compared to EN19. EN24 is commonly used in aerospace, automotive, and high-performance engineering applications.

EN31 is a high-carbon alloy steel mainly used for bearings, dies, tools, and wear-resistant components due to its excellent hardness and abrasion resistance.

EN41B alloy steel is best suited for applications that require high surface hardness, excellent wear resistance, and core strength.

Yes, many alloy steel grades can be welded using proper welding procedures and pre/post-heat treatment methods depending on the grade composition.

Alloy steel provides better mechanical properties, higher wear resistance, improved toughness, and enhanced heat resistance compared to ordinary carbon steel.

EN8 alloy steel is a medium carbon steel known for its good strength, toughness, and machinability. It is widely used for engineering applications that require moderate wear resistance and durability.
