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 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. 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.
• Normalizing of EN8 bright mild steel takes place at 830-860°C (1526°F-1580°F) then it is cooled in air.
• Quenching in oil or water after heating to this temperature will harden the steel.

En 353 steel has carbon content of 0.17% and the most common form of steel as it’s provides material properties that are acceptable for many automobile applications such as heavy duty gear, shaft, pinion, cam shafts, gudgeon pins [1,8]. It is neither externally brittle nor ductile due to its lower carbon content and lower hardness. As the carbon content increases, the metal becomes harder and stronger.

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 [3]

Application:

• Machining components, Gears.

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.
• 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.

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.

EN45 is a manganese spring steel. That is to say, it is a steel with a high carbon content, traces of manganese that effect the metal’s properties, and that it is generally used for springs (such as the suspension springs on old cars). It is suitable for oil hardening and tempering. When used in the oil hardened and tempered condition EN45 offers excellent spring characteristics. EN45 is commonly used in the automotive industries for the manufacture and repair of leaf springs. Tempered EN45. The typical re-enactor’s weapon is made from hardened and tempered EN45. These weapons are made by professional smiths, and their properties depend substantially on the skills and choices made by the smith. Much depends on the hardness to which the blade is tempered. The Rockwell scale is generally used as a measure of this hardness. I believe that at the present date most UK armourers temper to between 52 and 54 on this scale. Harder blades are more likely to suffer from chips and breakage, while softer blades are more likely to bur and require more frequent maintenance. To begin with all tempered swords swill pick up more damage than they will later in their life. This is because of the process of work hardening: every blow compacts the metal on the edge of the sword making it more resistant to future blows.

Applications:

• EN45 is used widely in the motor vehicle industry and many general engineering applications.
• Typical applications include leaf springs, truncated conical springs, helical springs and spring plates.

Forging:

• Preheat the EN45 carefully, then raise temperature to 1050°C for forging.
• After forging cool slowly, preferably in a furnace. Soak for 1 hour at 2150 F (1177 C) prior to forging.
• Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.

Annealing:

• Heat slowly to 640-680°C, soak well. Cool slowly in the furnace.

Tempering:

• Temper the EN45 spring steel immediately after quenching whilst tools are still hand warm.
