Forging

Pre heat carefully, then raise temperature to 850-1200°C for forging. Do not forge below 850°C. After forging cool slowly in still air.

 

Annealing:

• Heat the EN19T slowly to 680-700°C. Cool in air.

Hardening:

• Temper as soon as tools reach room temperature.

Tempering:

• Heat carefully to a suitable temperature selected by reference to a tempering chart or table.
• Soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air.
• Tempering between 250-375°C is not advised as tempering within this range will reduce the impact value.

EN8 also know as 080M40. Unalloyed medium carbon steel. EN8 is a medium strength steel, good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. AISI 1040. Available as normalized or rolled. EN8 is supplied asround drawn/turned, round hot rolled, hexagon, square, flats and plate. EN8 is usually supplied untreated but can be supplied to order in the normalized or finally heat treated (quenched and tempered to ”Q” or “R”properties for limiting ruling sections up to 63mm), which is adequate for a wide range of applications. Please refer to our selection guide for comparisons. EN8 is a very popular grade of through-hardening medium carbon steel, which is readily machinable in any condition. (Refer to our machinability guide). EN8 is suitable for the manufacture of parts such as general-purpose axles and shafts, gears, bolts and studs. It can be further surface-hardened typically to 50-55 HRC by induction processes, producing components with enhanced wear resistance. For such applications the use of EN8D (080A42) is advisable. It is also available in a free-machining version, EN8M (212A42), EN8 in its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. Good heat treatment results on sections larger than 63mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. It is therefore recommended that larger sizes of EN8 are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal. This should achieve better mechanical properties towards the core.

Heat Treatment:

• EN8 or 080m40 can be tempered at a heat of between 550°C to 660°C (1022°F-1220°F), heating for about 1 hour for every inch of thickness, then cool in oil or water.

Welding:

• Modern EN8 bright mild steel contains a lot less carbon then it uses to, this mean that it is possible to weld pieces up to 18mm thick without preheating using MIG wire (SG2) or a 7018 electrode.
• Over 18mm would require a pre-heat of 100°C (212°F) in order to prevent cracking.
• Anneal afterward is recommended to prevent breaking

EN36C gives a hard case with a strong core, whilst retaining a remarkable degree of toughness.

 

Carburizing/ Case Hardening:

• Case hardening will give a hard wear resisting surface and tough core strength to the steel.
• Case hardening temperatures range from 860-960°C, followed by rapid quenching which will determine the resulting hardness.

Tempering:

• For optimum toughness temper at low temperatures for a minimum of 2 hours.
• The case hardness should be in the region of 60-62HRc.

Softening:

• If it is necessary to soften the EN36 for machining between the carburising and subsequent heat treatment stages, heat to 640-650°C.
• Soak at this temperature for 1 to 2 hours and cool slowly in the furnace or in air.

Heat Treatment:

• Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN36 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 EN36 case hardening steel.

EN24 is usually supplied in the finally heat treated condition (quenched and tempered to “T” properties) up to a limiting ruling section of 250mm, which is superior to grades 605M36, 708M40 or 709M40 -see properties below. Please refer to our selection guide for comparisons. 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. 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. EN24 sections larger than 250mm may still be available in the quenched and tempered condition, but it should be noted that a fall-off in mechanical properties may be apparent approaching the centre of the bar. It is therefore recommended that larger sizes are supplied in the annealed (softened) condition, and that quenching and tempering is carried out after initial stock removal. This should achieve better mechanical properties towards the core. We stock EN24 in bright bar and blocks and black bar, square, flats and blocks.
