En Series Steel Grade EN 3 B

En Series Steel Grade EN 3 B


  • EN3B, also known as 070m20, available in rounds, flats, squares & hexagons. En3b is a mild steel suitable for welding and general machining. AISI 1020
  • The term mild steel applies to all low carbon steel that does not contain any alloying elements in its makeup and has a carbon content that does not exceed 0.25%. The term “mild” is used to cover a wide range of specifications and forms for a variety of steel.
  • Mild steel is used in mechanical engineering applications for parts that will not be subject to high stress.
  • When in its bright cold drawn condition the steel is able to endure higher levels of stress, particularly on smaller diameters.
  • Compared to normal mild steel, bright mild steel provides tighter sectional tolerances, increased straightness, and a much cleaner surface. The main advantage of cold drawn steel is that steel can be bought closer to the finished machine size, providing reduce machining costs. Another benefit of bright steel bars is a marked increase in physical strength over hot rolled bars of the same section.
  • EN3B bright mild steel (070m20) used to be the most popular specification of bright mild steel available. It has since been replaced by steels that have a tighter chemical analysis.
  • EN3b Bright mild steel is now a general purpose steel that is suitable for welding, can be case-hardened and is good for general machining. EN3b is generally used in engineering applications that will not be heavily stressed.

En Series Steel EN 45

En Series Steel EN 45


  • 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. Hardness is largely a matter of taste and choice once you know the properties of different blades, and claims are made for both hard and soft swords.

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. 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. 
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.
Tempering
  • Re-heat to 780C – 820C, hold until temperature is uniform throughout the section, and quench in oil,Temper immediately while still hand warm. Heat to 150C – 200C as required, Soak for 1 – 2 hours per 25mm of section, and cool in still air.
