We hope we can providebearing steel round bars with the best price and high quality products for you.
diameter:10-600mm
diameter:10-600mm
hot rolled and forged or cold drawing
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, equalise, 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, equalise, then cool slowly.
Heat uniformly to 800/820°C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thickness.
