EN24 Flat Bars, Square, SAE 4340, 817M40, 34CrNiMo6

Description

EN24 Flat Bars & Square Bars

EN24 Flat Bars is a nickel chromium molybdenum combination – this offers high tensile steel strength, with good ductility and wear resistance characteristics. With relatively good impact properties at low temperatures, EN24 is also suitable for a variety of elevated temperature applications.

EN24 can be heat treated to a wide range of tensile strengths from 850-1000 N/mm² (‘T’ condition) up to 1550 N/mm² (‘Z’ condition). Heat treated EN24 offers high tensile strength combined with good ductility and resistance to shock. At low temperatures good impact values can be obtained.

EN24 is a very popular grade of through-hardening alloy steel, which is readily machinable in the “T” condition. EN24T is most suitable for the manufacture of parts such as heavy-duty axles and shafts, gears, bolts and studs. EN24T can be further surface-hardened typically to 58-60 HRC by induction or nitride processes, producing components with enhanced wear resistance.

In addition to the above, EN24T is capable of retaining good impact values at low temperatures, hence it is frequently specified for harsh offshore applications such as hydraulic bolt tensioners and shipborne mechanical handling equipment.

BS970: 1955 EN24, BS970/PD970: 1970 onwards 817M40. Related European grades: 34CrNiMo6, Werkstoff No. 1.6582. US Grade: SAE (AISI) 4340.

EN24 Chemical Composition :

EN24 steel equivalents :

Being such a popular alloy steel grade many countries around the world started producing their own versions of a nickel chrome moly high tensile steel. With some subtle differences in composition these are some examples of the foreign equivalents to EN24

EN24 Bar Machinability :

The machinability of EN24 in the annealed condition is approximately 53% of that for mild steel (070M20). When supplied as EN24T the machinability is approximately 35%-40% of that for mild steel (070M20).

EN24 applications :

• • Power transmission gears and other gears requiring maximum hardness.
• • Cranks, axles, propellor and gearbox shafts requiring good high tensile properties.
• • Connecting rods, special cranks and other parts required to be stiff and yet retain a high degree of toughness.
• • Bolts, screwed parts, stub axles, swivel arms required very tough.
• • Plastics and rubber moulding industry parts for moulds, hob retaining rings, stop pins.
• • Structural components with good high tensile needs.
