Cold Work Tool Steel Plates AISI O-1

Cold-work tool steels are high carbon steels that are further classified into three subgroups such as oil-hardening steels, high-carbon, high-chromium steels, and air-hardening steels. Oil-hardening cold-work steels are also known as group o steels consisting of o1, o2, o6, and o7 types.
Type o1 oil-hardening cold-work steel consists of chromium, manganese, and tungsten and is relatively inexpensive. The following datasheet provides details about o1 type.
Fabrication and heat treatment
machinability
the machinability of o1 steels is very good with a rating of 90% that of water hardening low alloy steels.
Forming
o1 steels can be easily formed in the annealed condition using conventional methods.
Hardening
o1 steels should be heated uniformly to 780-820°c (1436-1508°f) until completely heated through. If needed, the steels can be preheated at 300-500°c (572-932°f). About 30 minper 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil.
