Starrett 54016 O1 Tool Steel Flat Stock 10x18 in

Product Description

The STARRETT 54016 is an O1 oil-hardening tool steel flat stock blank used in toolmaking, die making, and precision machining applications. Measuring 0.125 inches thick, 10 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a squareness tolerance of 0.003 inches per inch on all edges. Weighing 6.38 pounds, this piece is sized for shops that need a substantial working blank without custom ordering. O1 tool steel is a versatile, water-quench-compatible oil-hardening grade known for its dimensional stability during heat treatment and good machinability in the annealed state.

This flat stock is suited for fabricating punches, dies, gauges, jigs, fixtures, and cutting tools in tool and die shops, machine shops, and maintenance departments. It is appropriate for both one-off tooling and short-run production of precision components where tight tolerance pre-hardened or ready-to-harden stock is required. The generous 10-inch width and 18-inch length provide flexibility for layout and blanking multiple parts from a single piece.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat treat response and dimensional stability
• Thickness tolerance of plus or minus 0.001 inches for accurate starting dimensions
• Width tolerance of 0.000 to minus 0.015 inches ensures the blank does not exceed nominal width
• Length tolerance of plus 0.250 inches, minus 0 inches provides material for facing to final length
• Squareness held to 0.003 inches per inch on all edges, reducing setup time
• Annealed condition allows machining before hardening

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock blank suitable for toolmaking, die making, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with O1 steel properties. Follow the material manufacturer's recommended annealing, hardening, and tempering cycles for AISI O1. Use appropriate cutting fluids during machining to manage heat buildup. Personal protective equipment including safety glasses and heat-resistant gloves is required during any heat treatment operations.
