Measuring 0.375 inches thick, 4 inches wide, and 18 inches long, it is ground to close tolerances and supplied in an annealed condition ready for machining before heat treatment. A2 tool steel offers good dimensional stability during air hardening, making it a preferred choice for punches, dies, gauges, and cutting tools where tight post-heat distortion is a priority. This flat stock is handled and installed by tool and die makers, machinists, and fabricators working in production or job shop environments.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating precision tooling components in both production and custom shop settings. The 18-inch length provides a practical starting blank for cutting multiple smaller blanks or machining a single longer component. The 4-inch width accommodates a wide range of die plate and punch holder profiles without requiring additional welding or joining. A2 material specification meets AISI Type A2 standards, making it appropriate for applications requiring moderate toughness combined with good wear resistance after hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type A2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +0.010 to 0.015 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eReady-to-machine annealed flat stock in a single-piece package quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 tool steel flat stock blank suitable for use in conventional milling, grinding, and EDM operations prior to air-hardening heat treatment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with tooling alloys. All cutting, grinding, and finishing operations should be completed before hardening. Use appropriate personal protective equipment when cutting or grinding tool steel.
