Heat treatment Related
Annealing of O1 Tool steel
Slowly heated to ******0 ºC(********0ºC) and allow enough times,
let the steel to be thoroughly heated, Then cool slowly in the
furnace. The o1 tool steel will get MAX **0 HB (Brinell
hardness).
Hardening of o1 tool steel
O1 steels should be heated uniformly to ******0°C (********8°F)
until completely heated through. If needed, the steels can be
preheated at ******0°C (******2°F). About *0 min/per *5 mm of
ruling section is to be provided and then the steels should be
immediately quenched in oil.
Tempering of o1 tool steel
Tempering of O1 steels is performed at ******0°C (******2°F), Soak
well at the selected temperature and soak for at least one hour per
*5mm of total thickness. Get Rockwell C hardness of *5 to *4.

Applications
O1 steels are mainly used for short run tooling for cold forming
dies, blanking dies, and cutting tools operating at ambient
temper.
O1 tool steel typical applications include medium run dies,
intricate press tools, drawing punches, broaches, bushings, lathe
centres, chuck jaws, master cavity sinking hobs, paper cutting
machine knives, plug gauges, thread gauges and precision measuring
tools. Also commonly used in applications such as cams, cloth
cutting knives, cold taps, reamers, collets, cutting hobs, strip
slitting cutters, trimmer dies, tube expander rolls, plastic moulds
and woodworking knives ature.
