Measuring 0.375 inches thick, 6 inches wide, and 18 inches long, this flat bar is manufactured from AISI A2 tool steel, a chromium-based air-hardening grade known for its dimensional stability through the heat-treat cycle and good wear resistance. Thickness, width, and squareness tolerances are held to +0.010 to 0.015 inches, and length tolerance is +0.25 inches, giving machinists a consistent oversize blank to finish to final dimension.\u003c\/p\u003e\n\u003cp\u003eA2 flat stock at this cross-section is commonly used in tool-and-die shops, maintenance and repair operations, and precision machine shops. Typical applications include blanking dies, form punches, gauges, and wear plates where moderate toughness and predictable air-hardening response are required. At 0.375 inches thick and 6 inches wide, the blank provides enough cross-section for most medium-duty tooling layouts without the need to rip down a larger bar. This stock is sold in single-piece quantities, making it practical for prototype and low-volume tooling projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n  \u003cli\u003e0.375 inches thick by 6 inches wide by 18 inches long — ready-to-machine flat blank\u003c\/li\u003e\n  \u003cli\u003eThickness, width, and squareness tolerances of +0.010 to 0.015 inches for consistent stock removal\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of +0.25 inches provides full usable length after facing\u003c\/li\u003e\n  \u003cli\u003eSingle-piece minimum order quantity for prototype and short-run tooling needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose A2 air-hardening tool steel flat stock blank suitable for use in tool-and-die, maintenance machining, and precision fabrication applications requiring AISI A2 material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and heat treating of tool steel should be performed by qualified machinists and heat-treat technicians following accepted shop practice. Material should be deburred and cleaned prior to heat treatment. Always consult the material manufacturer's published heat-treat data for A2 tool steel before hardening, tempering, or stress relieving. Appropriate eye and hand protection must be worn during all cutting, grinding, and handling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.47 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 57194\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541262106930,"sku":"57194","price":678.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_f9bece01-597f-4a2f-9cf7-73d829fa8065.jpg?v=1785871024","url":"https:\/\/voomisupply.com\/products\/starrett-57194-a2-tool-steel-flat-stock-3-8x6x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
