Starrett 54513 O1 Tool Steel Flat Stock 1x12x36 in

Product Description

The STARRETT 54513 is an O1 oil-hardening tool steel flat stock bar measuring 1 inch thick, 12 inches wide, and 36 inches long. Manufactured to AISI Type O1 material specification, this flat stock is machined from tool steel and held to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a squareness tolerance of 0.003 inches per inch on all edges. At 122.38 pounds, this is a heavy-duty bar suited for tool and die shops, machine shops, and industrial fabrication environments. Licensed machinists, toolmakers, and metalworking professionals use this stock to produce punches, dies, gauges, and precision cutting tools.

This flat stock is intended for applications that require a machinable tool steel blank that can be hardened in oil after machining. The O1 alloy offers good machinability in the annealed state before heat treatment, making it a common choice for toolroom and production die work. Typical applications include the fabrication of blanking dies, form tools, bushings, and other tooling components where tight dimensional accuracy is required before and after hardening. The large 12-inch width and 36-inch length provide ample material for cutting multiple blanks from a single piece.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate metalworking equipment. Secure the workpiece properly before any cutting or milling operation. Heat treatment, including oil hardening, should follow established metallurgical procedures and applicable shop safety protocols. Handle the bar with care given its weight of 122.38 pounds; use mechanical lifting aids where required.
