This flat stock measures 0.125 inches thick, 1.25 inches wide, and 18 inches long, with a weight of 0.8 pounds per piece. A2 tool steel is known for its good dimensional stability during heat treatment and its balance of toughness and wear resistance, making it a practical choice for general toolroom work where air-hardening steel is specified.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for toolroom and light manufacturing environments, including job shops, maintenance shops, and production facilities that machine, grind, or fabricate tooling components. It ships as a single piece and can be cut, milled, or ground to finished dimensions before or after hardening. The 18-inch length provides enough stock for multiple smaller parts or a single longer tool blank. Professionals specifying AISI A2 air-hardening tool steel for stamping tooling, gauging plates, or custom fixtures will find this bar a direct fit for those applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness: 0.125 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 1.25 inches with a tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with a tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of +0.010 to 0.015 inches for consistent cross-section geometry\u003c\/li\u003e\n\u003cli\u003eSold as a single piece, minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flat bar blank for toolroom fabrication applications requiring AISI A2 air-hardening tool steel in a 0.125-inch by 1.25-inch cross-section profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by a qualified machinist or toolmaker following accepted toolroom practices. Always follow appropriate safety procedures when cutting, grinding, or hardening tool steel, including the use of proper personal protective equipment. Heat treatment processes, including austenitizing temperature and quench method, should follow the material manufacturer's published guidelines for AISI A2 steel.
