| Application | 65Mn high carbon steel is mainly used in the manufacture of various small-section flat springs, round springs, clockwork, etc. It can also be used to manufacture spring rings, valve springs, shock absorbers, clutch reeds and brake springs, regulating speed regulating spring, spring load, general machinery in the round, square spiral spring or pull wire for small mechanical spring. | |
6. Heat treatment Related
Annealing
At first Slowly heated to 730 ºC and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Then 65Mn tool steel will get MAX 250 HB (Brinell hardness).
Hardening
At the beginning, 65Mn steels should be heated uniformly to 830-860°C (1526-1580°F) until completely heated through. After about 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil.
Tempering
65Mn steels is performed at 540°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Hardness values at different temperatures after tempering.
7: Delivery condition
For hot forged rolled bar, usually the delivery condition is hot forged or rolled, annealed/QT, rough turned/Black surface.For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
