O1 Tool Steel Tempering Chart

Minimizing warpage is another.

O1 tool steel tempering chart. When the high temperature heating is carried out in a salt bath the range of temperatures should be about 15ºc 25ºf lower than given in this line. O1 is a general purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness strength and wear resistance. The road to success is to evenly heat the metal. Heat treating o1 tool steel is simple.

Heat treating tool steels manufacturing table chart. Tempering of o1 steels is performed at 177 260 c 350 500 f to realize rockwell c hardness of 62 to 57. Hardening steel is the easy part. O1 tool steel is the original oil hardening non shrinking tool steel that can be hardened to the rockwell c 65 range from a low austenitizing temperature.

The tempering table shows the hardness values obtained at various tempering temperatures on a two inch cube of steel hardened from 1475 f and tempered two hours. In the following discussions the terms steel tool steel and carbon steel should be understood as referring to o 1. When repair welding of the o1 tool steel in hardened and tempered condition the steel should be preheated to a minimum tempering temperature of 200 c 93 f and welded at the same tempering temperature.
