EN24 steel 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 high-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.
EN24 was originally introduced for use in the motor vehicle and machine tool industries for gears, pinions, shafts,
spindles and the like. Later its applications became much more extended. Suitable to produce parts for such as
locomotives, cranes, rolling mills, coal cutting machinery etc. where good strength and fatigue resistance is called
for. Other applications for EN24 and EN24T are found in die casting and hot metal working, such as die bolsters,
racks and pinions, angle pins for pressure die casting, hot stamping dies for aluminium stamping, die beds for steel
stamping, lower temperature nut, bolt and rivet heading dies, large section drop forging dies.
It is widely used in the
plastic and rubber moulding industries for moulds (particularly rubber moulds), hob retaining rings, patens, retaining
rings for built up moulds, stop pins for moulds. For moulds EN24 is normally supplies hardened and tempered to
‘T’ condition. If a higher hardness is desired EN24T should be annealed and then heat treated to the required
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as
the shape and size of each steel component. Other considerations during the heat treatment process include the
type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider
for full guidance on heat treatment of alloy steel.
