Value Collection NS06266282 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS06266282 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 1 inch wide, and 36 inches long. O1 tool steel is a cold-work steel known for its consistent hardness response, good wear resistance, and dimensional stability through the oil-quench hardening process. This flat stock ships in the annealed condition and is intended for machining, grinding, or cutting to final shape before heat treatment. Machinists, tool makers, and die makers select O1 flat stock when tight dimensional tolerances and predictable hardening behavior are required for punches, dies, gauges, and cutting tools.

This flat stock is suited for tool rooms, job shops, and maintenance shops producing custom tooling, fixtures, and wear components. It is appropriate for both light-production and one-off tooling applications where the part will be finish-machined and then oil hardened to final hardness. The AISI Type O1 material specification ensures consistency across the cross-section. Stock dimensions of 1 inch by 1 inch by 36 inches allow a single bar to yield multiple tool blanks depending on the application.

Key Features

• AISI Type O1 oil-hardening tool steel material specification
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal during machining
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Annealed condition allows machining prior to hardening

Compatibility

Designed as a general-purpose O1 tool steel flat bar for tool room and machining applications requiring oil-quench hardening; verify fitness for specific tooling applications based on required hardness, cross-section, and service conditions.

Installation Notes

Machining and cutting of this flat stock should be performed in the annealed condition using standard metalworking equipment appropriate for tool steel. Hardening requires controlled heating to austenitizing temperature followed by an oil quench — this work should be performed by personnel familiar with heat-treatment procedures for O1 tool steel to avoid cracking or distortion. Allow the bar to reach ambient temperature before measuring finished dimensions after heat treatment. Follow applicable shop safety practices when handling and cutting tool steel bar stock.
