Manufactured from AISI Type O1 tool steel, this flat stock is supplied in the annealed condition, ready for machining, grinding, and subsequent oil-quench hardening by a tool and die maker or machinist. The bar measures 3\/32 inch thick, 1-1\/2 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inch. Weight is 1.46 pounds per bar. O1 is a widely used oil-hardening grade known for its good dimensional stability during heat treatment and ease of machining in the annealed state.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for producing punches, dies, gauges, lathe centers, taps, reamers, and other tooling components that require moderate wear resistance and good hardness after heat treatment. The 36-inch length allows a machinist to cut multiple blanks from a single bar. The 3\/32-inch thickness is appropriate for thin tooling components, shims, and wear strips where precise ground dimensions are required before hardening. Each bar ships individually, with a minimum order quantity of one piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel in annealed condition, ready for machining and grinding\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for tight dimensional control\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inch\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inch\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inch per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWeighs 1.46 pounds per bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock bar suitable for use in tool and die, moldmaking, and precision machining applications where oil-hardening tool steel stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is machined and ground by qualified tool and die makers or machinists prior to heat treatment. Hardening involves heating to the appropriate austenitizing temperature and quenching in oil, followed by tempering; consult a recognized heat-treatment reference or material data sheet for proper thermal cycles before processing. Use appropriate personal protective equipment and ventilation when machining, grinding, or heat-treating tool steel. Store bar stock flat to prevent warping and protect ground surfaces from corrosion prior to use.\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 Type O1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to minus 0.005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inch per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.46 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: 54283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538950127922,"sku":"54283","price":145.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_84e9b4a9-e4c1-46dd-977c-ab7cbbe803e8.jpg?v=1785830625","url":"https:\/\/voomisupply.com\/products\/starrett-54283-o1-tool-steel-flat-stock-3-32x1-1-2x36in","provider":"Voomi Supply","version":"1.0","type":"link"}
