Starrett 54432 AISI O1 Tool Steel Flat Stock 7/16" x 2" x 36"

The Starrett 54432 is a precision flat stock bar made from AISI O1 oil-hardening tool steel, measuring 7/16" thick x 2" wide x 36" long. This versatile tool steel is ideal for manufacturing custom cutting tools, punches, dies, gauges, and precision tooling components.

Key Features:

• AISI O1 oil-hardening tool steel for superior dimensional stability
• Excellent for intricate work and thin sections with minimal risk of cracking
• Precision ground flat stock for accurate machining and fabrication
• Dimensions: 7/16" thickness x 2" width x 36" length
• Can be heat treated to achieve hardness ranging from 57-64 HRC
• Good wear resistance and edge retention when hardened

O1 tool steel is one of the most popular and versatile grades for toolmaking applications. It offers excellent machinability in the annealed state and can be readily hardened through oil quenching. The dimensional stability during heat treatment makes it particularly suitable for complex shapes and precision tooling where warpage must be minimized.
