    Applications
    This grade of steel is suited for shock loading or stress concentration applications such as shafts, gears, bolts, nuts, pins and couplings.
    Forging
    Preheat the steel carefully, then raise the temperature to 1150-1210°C for forging. Do not forge below 850°C. 4340 has good forging characteristics but care must be taken when cooling as the steel shows susceptibility to cracking. Cooling in ash or lime after forging is recommended.
    Annealing
    Heat the steel slowly to 800-860°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace.
    Stress Relieving
    When components are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening.
    Hardening
    4340 steel is usually supplied ready heat treated. If further heat treatment is required annealed 4340 should be heated slowly to 830-865°C and after adequate soaking at this temperature quench in oil. Temper as soon as the steel reaches room temperature.
    Tempering
    Heat the steel carefully to a suitable temperature selected by reference to a tempering chart or table, soak at the temperature for 2 hours per 25mm of section, then allow to cool in air.
    Heat Treatment
    Heat treatment temperatures, such as rate of heating, cooling and soaking times can vary due to factors such as the shape and size of each steel component. Other considerations during the heat treatment of 4340 include the type of furnace, quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.
