Measuring 0.375 inches thick, 2.5 inches wide, and 18 inches long, this bar is cut and ground to tight tolerances that make it ready for layout, machining, or heat treatment with minimal stock removal. A2 tool steel offers good dimensional stability during air hardening, making it a preferred material for punches, dies, blades, and gauges where distortion control is critical. Weighing 4.76 pounds, this piece is sized for single-unit job shop and maintenance toolroom use.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for toolrooms, machine shops, and maintenance facilities that fabricate or repair cutting tools, forming dies, and precision fixtures. A2 material is commonly specified when parts require moderate toughness combined with good wear resistance after hardening. The 18-inch length accommodates many standard toolroom applications without requiring additional sawing. It is also used in educational and vocational machine shop settings for toolmaking projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel with good dimensional stability during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eReady for machining, grinding, or direct layout work as received\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar suitable for general toolroom fabrication, die making, and fixture applications requiring tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting fluids and speeds for tool steel. Heat treatment to harden A2 material requires air-quench procedures and should be performed in a controlled atmosphere furnace to minimize scaling and decarburization. Always allow the material to reach ambient temperature before performing final grinding or tolerance-critical operations. Follow applicable shop safety procedures when handling freshly hardened tool steel, as brittle fracture risk increases before tempering.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.76 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54732\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539252740402,"sku":"54732","price":326.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_c4c1cfb7-9007-47fd-85a8-1ddd7792eed7.jpg?v=1785837160","url":"https:\/\/voomisupply.com\/products\/starrett-54732-a2-tool-steel-flat-stock-3-8x2-1-2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
