Application:
  • The low carbon steels, such as C15 are used for applications such as cold headed fasteners and bolts.

Stress Annealing:
  • Stress relieving to remove machining stresses should be carried out by heating to approx. 540°C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment

Machinability:
  • Machinability of C15 steel is fairly good, especially in the cold drawn or cold worked condition. Based upon carbon steel AIS11112 as a reference that is considered 100% machinable (easily machined) the C10 steel has a rating of 55%.

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.

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.

    Forging:
    • HForging of D2 steels can be done from 1065ºC (1950ºF) down to 954ºC (1750ºF). Do not forge below 926ºC (1700ºF).

    Annealing:
    • D2 is supplied in the annealed and machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened by the toolmaker. To anneal, heat slowly and uniformly to 900°C. Soak for three to four hours and allow to cool in the furnace to room temperature. Re-heat to 800-1040°C and again soak for three to four hours. Allow to cool in the furnace to room temperature.

    Hardening:
    • It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat the D2 tool steel component to 750-800°C. and allow to soak at this temperature. The tools may then be brought up to 1000-1040°C for air cooling, or 980°C for oil quenching. Soak thoroughly at the temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly. It is important not to exceed 1020°C when heating for hardening.

    Application:
    • Tool steel P20+S is ideally suited for the production of moulds where improved machinability is required. Typical applications include bolsters and injection moulds, die holders and zinc die casting dies. P20S is a versatile plastic mould tool steel with high tensile characteristics suitable for many other applications such as shafts and wear strips.A popular grade for toolmakers, D2 is used in a wide variety of tool making applications. Typical applications include blanking dies and punches for sheet in stainless steel, brass, copper, zinc and hard abrasive materials generally. Other application include deep drawing dies, cupping dies, forming dies, sheet metal forming rolls, shear blades for strip and sheet including flying shears, circular cutters for cold rolled strip,

    Principal Design Features:
    • This alloy is in the category generally labeled as Mold Steels. Nickel and chromium are the alloying elements for hardness and toughness. This alloy is most often used in the carburized condition.

    Tempering:
    • P20 tool steels are tempered at 482-593°C (900 to 1100°F) for a Rockwell C hardness of 37 to 28.

    Annealing:
    • Annealing takes place at 760-788°C (1400 to 1450°F) and then the steels are cooled slowly in the furnace at a temperature less than 4°C (40°F) per hour.

    Cold Working:
    • P20 tool steels are capable of being readily cold worked by using conventional tooling methods with the alloy in the annealed condition.

    Forging:
    • P20 tool steels are forged at 1093°C (2000°F) down to 899°C (1650°F). Forging below 871°C (1600°F) is not recommended for these steels.

    Heat Treatment:
    • P20 tool steels are heated to 871-899°C (1600-1650°F) in the carburizing medium during the carburizing process. After being carburized, these steels are heated to 816-871°C (1500-1600°F) in order to be hardened and then held for 15 minutes and finally oil quenched.

    Application:
    • P20 tool steels are used for low temperature applications that include injection molds and die casting dies.

    Final Grinding:

Wet grinding is a preferable option using a copious supply of coolant. If dry grinding is resorted to then use a very soft wheel.
