• EN1A is a very popular grade of low carbon-manganese free cutting steel, which is most suitable for the manufacture of repetition turned components, such as nuts, bolts, hydraulic fittings and studs, particularly where intricate drilling and machining operations are involved. It can be case-hardened, producing components with enhanced wear resistance.
• EN1A, also known as 230M07. EN1A is low carbon mild steel. Properties: free cutting, suitable for machining using both automatic and CNC machines. Available in square, round, flat or hexagon form. Equivalent to AISI 1113.

Chemical composition Mechanical Properties EN1A Equivalents Heat Treatment

• Carbonisation of EN1A bright mild steel takes place at 900-950°C (1652°F- 1742°F) then it is furnace or air cooled.
• En1A can be tempered at 180-210 °C (356 °F- 410°F) then should be left to cool in air.
• The mild steel can be hardened at 780-800°C (1436°F- 1472°F) then quenched in oil or water. However this is difficult to do with EN1A and is not recommended.

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.

EN9 steel stockholders and suppliers, delivering to the whole of South India.
EN9 is used commonly for many general engineering applications. Typical applications include, shafts, axes, knives, bushes, crankshafts, screws, sickles, wood working drills and hammers. 
Heat the steel slowly to 680-710°C, soak well. Cool slowly in the furnace. 
Heat slowly to 820-840°C, soak well. Cool slowly in the furnace.
Temper the EN9 steel component immediately after quenching whilst still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. For most applications tempering of EN9 will be between 550-660°C. Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN9 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 EN9 carbon steel.

• EN31 is a high carbon Alloy steel which achieves a high degree of hardness with compressive strength and abrasion resistance.

Forging

• Forge at 1000°/1050°C. Heat slowly, allowing sufficient time at the forging temperature for the steel to be thoroughly soaked through. Re-heat as often as necessary to keep the temperature above 850°C. After forging cool very slowly, preferably in a furnace.

Annealing

• Heat uniformly to 800°C, equalize, then furnace cool. (Hardness about 229 Brinell).

Stress Relieving

• If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalize, then cool slowly.

Tempering

• Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thickness.

Physical Properties Mechanical Properties Heat Treatment of EN-31 Hardening

• Heat uniformly to 800/820°C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil.

• EN41 is a chromium-aluminium-molybdenum nitriding steel usually supplied in the hardened and tempered condition. EN41 is supplied in round bar from stock and can be cut to your requirements. EN41 ‘R’ condition has a tensile of 700-850 N/mm². EN41’S’ condition has a tensile of 775-925 N/mm². It offers high wear resistant properties together with toughness and ductility. It is defined by its suitability for nitriding from which EN41 can give a hard wear resistant case up to 68HRc, better than achievable with the similar nitriding grade EN40B.

Chemical composition Applications

• EN41 is suited for applications that required excellent resistance to wear and abrasion. Typical applications include connecting rods, small extruders, valve stems, dies. It is widely used in the automotive, textile and general engineering industries. Suitable for applications requiring a resistance to wear, it is also suitable for other applications such as brick press plates, clutch plates, gudgeon, track and shackle pins.

Annealing

• Heat slowly to 650-700°C. Cool in air.

Hardening

• EN41 is supplied ready heat treated. If further heat treatment is required annealed EN41 should be heated slowly to 870-930°C and after adequate soaking at this temperature quench in oil/polymer or water. Temper as soon as tools reach room temperature.

Tempering

• Heat carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 580-700°C). Soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in the air.

Equivalents 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 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 EN41 alloy nitriding steel.

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