Show full description

14-08-2025 - tool steel bar-rectangle o1 - 1000x1000superZoom-main

Tool Steel Rectangle Bar O1

Tool Steel Rectangle/Flat Bar O1 is an 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. O1 tool steel has deep hardening properties and fine grain structure with unusual toughness.

We carry Ground Oversized O1 & Precision Ground O1 rectangle bar.
