What material is 817M40?
high tensile alloy steel
Description: 817M40 is a high tensile alloy steel, usually supplied in the heat treated T condition, although several heat treatments are available with specification limitations on size. The steel exhibits good shock and wear resisting properties. Main uses include gears, bolts and studs, shafts spindles and forgings.
Is EN24T stainless?
EN24T steel is a popular grade of through-hardening alloy steel due to its excellent machinability in the “T” condition. EN24T is used in components such as gears, shafts, studs and bolts, its hardness is in the range 248/302 HB….

What is the difference between EN24 and EN24T?
EN24 and EN24T Steel EN24 is a very popular grade of through-hardening alloy steel, which is readily machinable in the “T” condition. (Refer to our machinability guide). EN24T is most suitable for the manufacture of parts such as heavy-duty axles and shafts, gears, bolts and studs.
What is en in steel?
The meaning of EN is ‘European standard’ or ‘Euronorm’. It has replaced the term BS (i.e, British Standard). In the European Union, it’s standard are mainly use for business. The first two words in the En steels name is the European steel standard, After that the number is the standard number.
What is EN24T used for?
EN24T also benefits from good hardenability and wear resistance and is an ideal material for use in the production of dies and punches. Due to its hardenability capabilities, EN24T is used extensively in heavy duty applications where hardness, wear resistance and tensile strength is of prime importance.
What is EN24 hardness material?
248/302 HB
EN24T is used in components such as gears, shafts, studs and bolts, its hardness is in the range 248/302 HB. EN24T can be further surface-hardened to create components with enhanced wear resistance by induction or nitriding processing.
Is EN24 high carbon steel?
EN24 is a very high strength steel alloy which is supplied hardened and tempered. The grade is a nickel chromium molybdenum combination – this offers high tensile steel strength, with good ductility and wear resistance characteristics.
Can you weld EN24T?
EN 24 or AISI 4340 material if in annealed condition can be welded without much concerns. For steel in quenched & tempered condition is difficult to weld and welding of such type should be avoided.
What is 817m40 steel?
817M40 is a high tensile alloy steel, usually supplied in the heat treated T condition, although several heat treatments are available with specification limitations on size. The steel exhibits good shock and wear resisting properties.
What is BS 970 817m40 (en24t material)?
The following tables summarize BS970 817M40 (En24T Material), En24 steel properties, and specification including chemical composition, mechanical properties, hardness, heat treatment, etc. EN24 steel (En24T steel) and BS970 817M40 material chemical composition is listed in the following table.
What is the difference between 817m40t and en24t?
EN24T properties, composition and equivalents here. 817M40T is renown for its wear resistance properties and also were high strength properties are required. Typical chemical composition of 817M40. A range of popular 817M40 size ranges can be found on the EN24T stock page, other sizes available upon request.
How do you harden 817m40?
If further heat treatment is required annealed 817M40 should be heated slowly to 830-850°C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature. Hardening from a neutral salt bath, will reduce the possibility of scaling or decarburisation.
