Starrett 54514 O1 Tool Steel Flat Stock 1-1/8x1-1/2x36 in

Product Description

The STARRETT 54514 is an O1 oil-hardening tool steel flat stock bar measuring 1-1/8 inches thick, 1-1/2 inches wide, and 36 inches long. Manufactured to AISI Type O1 material specification, this flat stock is used by machinists, toolmakers, and die makers who need a consistent, machinable blank that responds predictably to oil-hardening heat treatment. Thickness tolerance is held to +/- 0.001 inches, giving fabricators a tight-tolerance starting point before final grinding or machining. The bar weighs 17.21 pounds. It ships as a single piece and is intended for professional shop use where dimensional accuracy matters before any heat treat cycle begins.

O1 tool steel flat stock in this size range is commonly used in tool-and-die shops, maintenance machining operations, and custom fixture fabrication. It is appropriate for making punches, dies, gauges, cutting tools, and general toolroom components where oil-hardened hardness and wear resistance are required after heat treatment. The 36-inch length provides sufficient stock for most single-component toolroom applications without requiring additional cutting from larger bar stock.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat treat response

• Single-piece packaging with no minimum order above one unit

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar suitable for general toolroom, die-making, and fixture fabrication applications requiring AISI Type O1 material specification.

Installation Notes

Cutting, grinding, and machining should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. All heat treating operations, including oil-hardening and tempering cycles, must be performed by qualified personnel following established metallurgical procedures for AISI O1 tool steel. Wear appropriate PPE when cutting or grinding tool steel. Consult applicable shop safety standards before beginning any heat treat operation.
