Chemical Analysis:

  • In order to ensure the material of the specimen is done with help of the optical emission spectroscope (OES).
  • The result is obtain from the chemical analysis, carbon – 0.171 %, silicon – 0.3 %, manganese – 0.56 %, phosphorus – 0.012 %, sulphur – 0.13 %, Chromium – 0.953 %, Nickel – 0.989 %, molybdenum – 0.16 % and remaining percentage is iron respectively.
  • A sample of 30 × 10 mm is polished using 60 grit papers and two sparks is introduced on the surface to find the chemical composition of the material.
  • After ensuring the chemical composition, the raw material is machined according to the dimension for various tests.

 

Hardness:
  • Vickers hardness measurements done on the specimen as per the IS 1501-2002 procedures by using Vickers hardness tester (MH6).
  • Hardness measurement is made with 200 g loads, dwell time of 10 seconds and diamond indenter is used for test.
  • The impression is done on the circular faces at the centre of the specimen.
  • The hardness values are taken corresponding to the diagonal length of the indentation.
  • Two samples (i.e. BHT and AHT) and five readings are taken from the each sample from case to core.
  • The average value is calculated from five readings. The hardness values of BHT (case and core) samples are, 193.7 and 201.8 HV respectively.
  • The hardness values of AHT (case and core) samples are 684.5 and 387.8 HV respectively.
  • It is clearly noticed that the base material (BHT) has the low hardness.
  • The AHT specimen has high hardness when compared to the BHT sample.

Analysis:
  • X-Ray Diffractometer is one of the most powerful techniques for material structural analysis.

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.

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. Available as normalized or rolled. EN8 is supplied as round 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. 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.
  • Normalizing of EN8 bright mild steel takes place at 830-860°C (1526°F-1580°F) then it is cooled in air.

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.

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.

It is neither externally brittle nor ductile due to its lower carbon content and lower hardness.


Chemical Analysis:
  • In order to ensure the material of the specimen is done with help of the optical emission spectroscope (OES).
  • The result is obtain from the chemical analysis, carbon – 0.171 %, silicon – 0.3 %, manganese – 0.56 %, phosphorus – 0.012 %, sulphur – 0.13 %, Chromium – 0.953 %, Nickel – 0.989 %, molybdenum – 0.16 % and remaining percentage is iron respectively.
  • A sample of 30 × 10 mm is polished using 60 grit papers and two sparks is introduced on the surface to find the chemical composition of the material.

Heat treatment Procedure for EN353:
  • CARBURISING Pack, salt or gas carburize at 910C, holding for sufficient time to develop the required case depth and carbon content, Slow cool from carburizing temperature and re-heat to 870C, hold until temperature is uniform throughout the section, quench as required in water, oil or air cool.

Hardness:
  • Vickers hardness measurement is done on the specimen as per the IS 1501-2002 procedures by using Vickers hardness tester (MH6).
  • Hardness measurement is made with 200 g loads, dwell time of 10 seconds and diamond indenter is used for test.

Analysis:
  • X-Ray Diffractometer is one of the most powerful techniques for material structural analysis.
  • Bruker AXS D8 Advance X-Ray diffractometer fit with vertical goniometers, low and high temperature attachment. The angle range is 360°, the maximum usable angular is 3° to 135° and wavelength is 1.5406 Å. X-ray diffraction analysis is carried out under the following condition: Cu radiation, 40 KV voltage, 35 mA current and maximum angular speed 30°/s.
  • When the x-ray is passed into the substrate and it is reflected back to the detector the angle made by the reflected ray to the substrate is denoted as . The value of is increased by changing the position of specimen by keeping the as reference β, D, ε, ρ are calculated. The different values are obtained by the varying value for certain range.
