Drill Rod Tool Steels 03719531 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03719531 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, machinists, and industrial maintenance professionals who require a reliable, machinable steel blank in the annealed condition. A2 tool steel offers good dimensional stability during heat treatment and moderate wear resistance, making it a widely used choice for punches, dies, gauges, and general tooling applications. This bar measures 5/16 inches thick, 6 inches wide, and 36 inches long, with tightly controlled tolerances on all dimensions to support accurate layout and machining prior to hardening.

This flat stock is suited for toolroom and production environments where stock must be cut, ground, or machined to final shape before heat treatment. A2 air-hardening steel is hardened in still air, which reduces distortion compared to oil-hardening grades, making it a practical choice for flat dies, blanking tools, forming tools, and precision fixtures. It is typically specified wherever moderate toughness and good wear resistance are required in a tool steel application.

Installation Notes

Machining, grinding, and cutting of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting fluids and personal protective equipment. Heat treatment of A2 tool steel should follow the material manufacturer's published hardening and tempering procedures and be performed in a controlled atmosphere or vacuum furnace to minimize decarburization. Always allow the material to fully normalize before beginning precision grinding operations after heat treat.
