Measuring 5\/32 inches thick, 5 inches wide, and 18 inches long, this flat stock is cut to size and ready for heat treatment or machining operations. A2 tool steel offers excellent dimensional stability during air hardening, moderate toughness, and good wear resistance, making it a reliable choice for punches, dies, and gauges. Tolerances are tightly held: thickness and width run +0.010 to 0.015 inches, square tolerance is +0.010 to 0.015 inches, and length tolerance is +0.25 inches. The piece weighs 4.02 pounds.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for tool and die shops, machine shops, and maintenance repair operations requiring A2 tool steel in a pre-cut flat bar form. Typical applications include blanking dies, forming dies, punches, wear plates, and precision gauging components. The 18-inch length provides enough stock for most small-to-medium tooling jobs without significant material waste. It is used by tool and die makers, machinists, and maintenance machinists in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for excellent dimensional stability during heat treat\u003c\/li\u003e\n  \u003cli\u003eDimensions: 5\/32 inches thick x 5 inches wide x 18 inches long\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance: +0.25 inches\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003ePre-cut flat bar format minimizes prep time before machining or hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI A2 tool steel flat bar suitable for general toolmaking, die making, and precision machining applications requiring air-hardening tool steel stock.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA2 tool steel flat stock is machined and heat treated by qualified tool and die makers or machinists.
