How do you harden O1 tool steel oil?

How do you harden O1 tool steel oil?

The heat treatment requires O1 steels to be slowly preheated to 649°C (1200°F) and then heated at 788-816°C (1450-1500°F). Then these steels should be held at the same temperature for 10 to 30 minutes and finally oil quenched.

Does O1 tool steel work harden?

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. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.

How hard can 01 tool steel get?

O1 grade steel is an oil-hardening, non-deforming tool steel. It is considered to be a “non-shrinking” steel and it can be hardened to a Rockwell Range of C 65 through use of relatively low temperatures.

How do you harden tool steel?


  1. Hardening. involves controlled heating to a critical tem- perature dictated by the type of steel (in the range 760- 1300°C) followed by controlled cooling.
  2. Tempering. involves reheating the hardened tool/die to a temperature between 150-675°C, depending on the steel type.

Is 01 a high carbon steel?

What is O1 steel composition? O1 contains high carbon content which improves its overall hardening and hardenability whole giving it higher wear resistance.

How do you heat treat an o1 drill rod?

Hardening O-1 Drill Rod: In a control temperature oven, heat slowly to between 1450-1500°F (788-843°C), and should have a cherry red color. Immediately quench it in oil, inserting it straight into the oil, moving it up an down motion vertically, not an angle. This will prevent the metal from warping.

What is oil hardening drill rod?

Oil hardened drill rods are easily welded and machined and are very tough and durable. During the oil hardening process, the rod is heated until glowing red then plunged into a vat of warm oil. This causes the surface to become extremely hard. Oil hardened drill rods are used for general tool making.
