Value Collection NS83286369 O1 Tool Steel Flat Stock

Product Description

The VALUE COLLECTION NS83286369 is an O1 oil-hardening tool steel flat stock bar used in toolmaking, die work, jig fabrication, and precision machining applications. Manufactured to AISI Type O1 specification, this flat stock measures 2 inches thick by 2 inches wide by 18 inches long and weighs 20.64 pounds. O1 tool steel is known for its dimensional stability during heat treat and its responsiveness to oil-quench hardening, making it a go-to material for machinists and toolmakers who need consistent, predictable results from rough stock to finished tool.

This flat stock suits job shops, tool and die operations, and maintenance machining environments where O1 stock is cut, ground, and hardened into punches, dies, gauges, and fixtures. The 18-inch length provides enough material for most single-piece tooling applications. The tight dimensional tolerances allow machinists to work closer to finish dimensions before hardening, reducing grinding time after quench.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening response
• Thickness tolerance of +/- 0.001 inches for close-to-finish stock removal
• Width tolerance of +0.005 / -0.000 inches
• Length tolerance of +0.250 inches
• Squareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness
• Weighs 20.64 pounds, sized for single-piece tooling blanks

Compatibility

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

Installation Notes

O1 tool steel flat stock is worked by machinists and tool and die makers using conventional milling, grinding, and sawing equipment. Follow AISI O1 preheat and oil-quench hardening procedures per the applicable heat treat specification before placing hardened components into service. Wear appropriate PPE when cutting or grinding tool steel. Consult material safety data and applicable shop safety standards before beginning thermal processing.
