Drill Rod Tool Steels 81177115 Alloy Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 81177115 is a pre hardened alloy steel flat stock bar measuring 36 inches long, 6 inches wide, and 1 inch thick. Manufactured to AISI/SAE Type 4142 specification, this flat stock delivers consistent hardness and strength throughout the cross section, making it well suited for machining, tooling, fixtures, dies, and structural applications where dimensional accuracy is critical. At 60.91 pounds, this is a substantial piece intended for shop and industrial use. Licensed machinists, tool and die makers, and industrial fabricators typically work with this material in production and job shop environments.

AISI/SAE 4142 alloy steel is a chromium-molybdenum grade known for good toughness and wear resistance in the pre hardened condition. This flat stock is appropriate for applications such as jigs, fixtures, die shoes, machine components, and support plates. The pre hardened condition eliminates the need for additional heat treatment in most standard tooling and structural applications, allowing the material to go directly from saw to machining operations. It is suitable for use in light industrial, heavy manufacturing, and maintenance and repair settings.

Key Features

• AISI/SAE Type 4142 chromium-molybdenum alloy steel in the pre hardened condition
• 36 inches long x 6 inches wide x 1 inch thick - substantial stock for large tooling and structural components

• Pre hardened condition allows direct machining without additional heat treatment in most applications
• Consistent cross-section hardness supports reliable performance in die, fixture, and machine component applications

Compatibility

Designed as an OEM-style replacement and general-use flat stock for applications requiring AISI/SAE Type 4142 pre hardened alloy steel in a 36 x 6 x 1 inch flat bar form.

Installation Notes

Cutting, drilling, and machining of alloy steel flat stock should be performed by qualified machinists using appropriate cutting tools rated for hardened steel. Always use proper workholding and personal protective equipment when sawing or milling this material. Follow applicable shop safety standards for material handling given the 60.91-pound weight of this piece. Consult your facility safety plan before lifting or repositioning stock of this size and weight.
