Starrett 54013 O1 Tool Steel Flat Stock 1/8x6x18 in

Product Description

The STARRETT 54013 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, machinable blank to grind or machine to final form before hardening. Conforming to AISI Type O1 material specification, this flat stock measures 0.125 inches thick, 6 inches wide, and 18 inches long, and weighs 3.83 pounds. Thickness tolerance is held to plus or minus 0.001 inches, providing the close dimensional control required for precision tooling applications such as punches, dies, gauges, and cutting tools.

This flat stock is suited for job shops, tool and die operations, and maintenance departments working in light manufacturing or precision fabrication environments. O1 tool steel machines readily in the annealed state, allowing full profile work before the oil-quench hardening process. It is appropriate for both one-off tool builds and short-run production of wear components. The 6 inch width and 18 inch length provide a practical blank size for a wide range of flat tooling geometries.

Key Features

• Finished dimensions: 0.125 inches thick, 6 inches wide, 18 inches long

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock blank suitable for precision tooling, die making, and gauge fabrication applications requiring close dimensional tolerances in the annealed condition.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Complete all profiling and drilling operations while the material is in the annealed state before performing the oil-hardening heat treatment process. Follow established heat treatment procedures and use appropriate personal protective equipment when handling hot steel and quench oil. Consult applicable shop safety standards and material data for heat treatment temperatures and quench procedures.
