What is O1 Tool Steel?

O1 Tool Steel is an oil-hardening, “non-shrinking” and versatile tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 Tool Steel is known as a low alloy steel because it contains several additives.

O1 steel is in compliance with SAE J437 and J438, ASTM A681, and DIN 1.2510.

What is O1 Tool Steel Used For?

O1 Tool Steel is a general-purpose tool steel that is commonly used in order to provide ample hardness, strength or wear resistance. It generally produces a strong edge and can be sharpened, however does not dull easily.  Therefore it is often used to make gauges, shims, stamps, jigs, cutters, , guides, levers, saws, knives, straight edges, fixtures, machine parts, punches, blanking dies, draw dies, forming dies, lamination dies, molding dies, swaging dies, screw dies and trim dies.

Heat Treatment

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