We are professional AISI 4340(34CrNiMo6,1.6582,SAE 4340)Forged Forging Steel Mining Excavator Slewing Bearing Ball Race factory from china
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. |
