Starrett 54457 AISI O1 Tool Steel Flat Stock 9/16" x 1" x 36"

The Starrett 54457 is a precision-ground flat stock made from AISI O1 oil-hardening tool steel, measuring 9/16" thick x 1" wide x 36" long. This high-quality tool steel is ideal for fabricating custom cutting tools, gauges, jigs, fixtures, and precision machine components.

Key Features:

• AISI O1 oil-hardening tool steel composition for excellent hardness and wear resistance
• Dimensionally stable during heat treatment, minimizing distortion
• Suitable for intricate work including thin sections with minimal risk of cracking
• Precision-ground to tight tolerances for consistent dimensions
• 36-inch length provides ample material for multiple projects
• Can be hardened to Rockwell C 57-62 for superior edge retention

O1 tool steel is a versatile, general-purpose tool steel that machines easily in the annealed condition and responds well to heat treatment. It offers an excellent balance of toughness, wear resistance, and machinability, making it the preferred choice for toolmakers and machinists working on precision applications.
