Conforming to AISI Type O1 specification, this flat stock measures 5\/32 inches thick, 2 inches wide, and 18 inches long. Thickness and squareness tolerances are held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy before hardening is critical. At 1.59 pounds, the piece is sized for bench-scale tooling work.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size is commonly used in tool and die shops, maintenance machining environments, and precision fabrication operations. Typical applications include punches, dies, gauges, cutting tools, jigs, and fixtures. The 18-inch length provides enough stock to cut multiple blanks from a single piece. This item ships as a single bar and is sold individually with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance blanks\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for consistent fit in tooling slots\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches, zero minus for full usable length\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eReady for machining, grinding, or direct heat treatment without additional conditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock blank suitable for tool and die applications requiring AISI Type O1 oil-hardening material in 5\/32 x 2 x 18 inch dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel flat stock should be performed by qualified machinists or toolmakers following established shop safety practices. Secure the workpiece properly before any machining operation. Heat treatment to full hardness requires controlled quenching in oil followed by appropriate tempering — consult AISI O1 heat-treat guidelines for cycle parameters. Avoid grinding dry without adequate coolant, as localized overheating can affect the metallurgical properties of the steel.\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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches, zero minus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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\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: 54034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541538701618,"sku":"54034","price":119.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_51e04817-3cb0-46c3-bdf1-703c8ffa58e8.jpg?v=1785878768","url":"https:\/\/voomisupply.com\/products\/starrett-54034-o1-tool-steel-flat-stock-5-32x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
