Starrett 54336 O1 Tool Steel Flat Stock 5/32x6x36 in

Product Description

The STARRETT 54336 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, fixture building, and precision machining applications. Manufactured to AISI Type O1 specifications, this flat stock measures 5/32 inches thick, 6 inches wide, and 36 inches long, and weighs 9.56 pounds. Thickness tolerance is held to +/- 0.001 inches, making it suitable for applications where dimensional consistency is critical before hardening. Licensed machinists, tool and die makers, and precision fabricators work with this material to produce punches, dies, gauges, and similar tooling components.

O1 tool steel flat stock in this size range is commonly used in job shops, toolrooms, and manufacturing environments where stock material is machined to near-net shape, then oil-quench hardened and tempered to the required hardness. The 6-inch width and 36-inch length provide enough material for a variety of blanks and plate-style tooling. This piece ships as a single bar at the listed dimensions.

Installation Notes

Tool steel flat stock requires machining by qualified personnel using appropriate metalworking equipment before heat treatment. Oil-hardening operations should follow established metallurgical procedures for AISI O1, including proper preheat, austenitizing temperature, and quench medium. Exercise all standard shop safety precautions when cutting, grinding, or heat-treating tool steel. Do not attempt hardening without adequate ventilation and appropriate personal protective equipment.
