The VALUE COLLECTION 0003105 is an A-2 air hardening tool steel flat bar cut to a stock length of 36 inches, 1 inch wide, and 0.25 inches thick. A-2 tool steel is a chromium-molybdenum air hardening grade known for excellent dimensional stability during heat treatment and good wear resistance. The decarb-free finish means the surface layer has not lost carbon content, making the material ready for grinding, machining, or hardening without requiring removal of a degraded outer zone. This bar is appropriate for toolmakers, machinists, and die makers working in job shops, maintenance departments, or production facilities.
A-2 tool steel flat stock at this size is commonly used in the fabrication of dies, punches, forming tools, gauges, and jig components. The 36-inch stock length provides a practical starting point for cutting multiple shorter blanks or machining a single longer tool component. The 0.25-inch thickness suits thin die sections and flat tooling applications where close tolerances after heat treat are required.
Designed as a standard stock-length A-2 tool steel flat bar suitable for general toolmaking, die making, and machining applications requiring an air hardening tool steel grade.
Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers using appropriate equipment and personal protective equipment. A-2 tool steel is air hardened and should not be quenched in oil or water. Grinding after hardening requires care to avoid surface burns that can reduce hardness and cause cracking. Follow material and shop safety standards applicable to your facility when handling and processing tool steel stock.
