Measuring 0.25 inches thick, 1.75 inches wide, and 36 inches long, this bar is ground to close dimensional tolerances and conforms to AISI A2 material specification. A2 tool steel offers good dimensional stability during heat treatment and moderate wear resistance, making it a reliable choice for toolroom applications where air hardening is preferred over oil or water quench processes.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for low-to-medium production tooling in job shops, tool and die rooms, and maintenance machining environments. The 36-inch length allows for multiple blanks to be cut from a single piece. Its pre-ground surface and tight thickness tolerance reduce setup time when used in surface grinding or milling operations prior to heat treat.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel — stable dimensions during heat treat with reduced warpage risk compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches; edge squareness 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eShips as a single 36-inch bar at approximately 5.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock bar for general toolroom use wherever AISI A2 air-hardening material is specified.

Follow established heat treat procedures for AISI A2 steel, including proper preheat and soak times, as specified by the material supplier or applicable shop standards. Eye protection, gloves, and appropriate chip guards are required during all cutting and grinding operations. Consult OSHA and applicable shop safety standards before beginning machining or heat treatment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 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 0.25 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.13 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: 57338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540617036082,"sku":"57338","price":326.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_4dfdeb81-3c2e-43fe-9e2c-75a81a1c3f6a.jpg?v=1785860185","url":"https:\/\/voomisupply.com\/products\/starrett-57338-a2-tool-steel-flat-stock-0-25x1-75x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
