Value Collection 35574151 O-1 Tool Steel Round Bar 1 in X 6 Ft

Product Description

The VALUE COLLECTION 35574151 is a decarb-free O-1 oil-hardening tool steel round bar stocked in a 6-foot length with a 1-inch diameter. O-1 tool steel is a general-purpose oil-hardening grade known for its good machinability and wear resistance in the annealed condition. The decarb-free surface means the outer layer retains its carbon content, eliminating the need to machine away a decarburized skin before hardening. This bar weighs approximately 20.7 pounds and holds a diameter tolerance of positive 0.005 to negative 0.015 inch. It is a standard stock item used by toolmakers, machinists, and die makers in job shops and manufacturing environments.

This round bar is suited for fabricating punches, dies, gauges, bushings, jigs, and other tooling components that require oil-quench hardening to achieve final hardness. The 6-foot stock length allows multiple parts to be cut from a single bar, reducing material waste. It is appropriate for both production shops and prototype environments where tight dimensional tolerances and consistent metallurgy are required before and after heat treatment.

Key Features

• Decarb-free surface preserves carbon content for consistent hardening response
• O-1 oil-hardening grade offers good machinability in the annealed state
• 1-inch diameter with a tolerance of positive 0.005 to negative 0.015 inch
• 6-foot stock length suitable for multi-part cutting layouts
• Ready for oil-quench heat treatment without additional surface preparation

Compatibility

Designed as a standard O-1 oil-hardening tool steel round bar suitable for toolmaking, die making, and general machining applications requiring oil-quench hardenable steel stock.

Installation Notes

Cutting and machining of tool steel round bar should be performed by qualified machinists using appropriate cutting fluids and tooling rated for alloy steel. All heat treatment operations, including oil quenching and tempering, should follow established metallurgical procedures for O-1 grade tool steel and be performed by qualified personnel. Wear appropriate PPE when cutting or grinding tool steel. Verify dimensional tolerances after any thermal process, as distortion can occur during hardening.
