Manufactured to AISI Type O1 specifications, this flat stock measures 1-1\/8 inches thick, 3 inches wide, and 36 inches long, with a weight of 34.43 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy is critical before and after heat treatment. Licensed machinists, toolmakers, and metal fabricators work with this material to produce punches, dies, gauges, and fixtures that require consistent stock dimensions.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is used primarily in job shops, tool and die shops, and precision machining operations. This bar stock is appropriate for applications requiring moderate wear resistance and good machinability in the annealed state. It is commonly rough-machined to near-net shape, then oil-quenched during heat treatment to achieve final hardness. The 36-inch length provides a practical working blank for most standard tooling and fixturing jobs. This stock ships in annealed condition and is intended for use by skilled tradespeople who will perform final shaping and heat treatment as required by the application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — good machinability in annealed state, oil-quench heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precise pre-machined dimensional control\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches maintains consistent cross-section\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches allows full usable length on every bar\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003e34.43-pound bar weight suitable for substantial tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock blank for toolmaking, die making, and precision fixture fabrication.

Secure the workpiece properly before any cutting operation to prevent movement. Heat treatment, including oil quenching, should follow established metallurgical procedures for AISI O1 tool steel and be performed only by personnel trained in heat-treating operations. Wear appropriate PPE including eye protection and heat-resistant gloves whenever handling or processing this material.\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: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\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: 34.43 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: 54516\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544213324082,"sku":"54516","price":1116.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_8982c731-19da-4f91-b910-188f093a6306.jpg?v=1785925733","url":"https:\/\/voomisupply.com\/products\/starrett-54516-o1-tool-steel-flat-stock-1-1-8x3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
