O1 Product Guide

Applications | Specifications | Mechanical and Chemical Data

Overview

Oil-hardening, general purpose tool steel that holds its size and shape with excellent accuracy when being heat treated. While not as strong or wear resistant as A-2 or D-2, it experiences significantly less distortion during the heat treating process. Typically used in rolls, punches, shear knives, food processing knives, and gauges.

Common Trade Names
