Starrett 54066 496 Series AISI O1 Tool Steel Flat Stock 7/32" x 4" x 18"

The Starrett 54066 is a precision ground flat stock made from AISI O1 oil hardening tool steel, measuring 7/32" thick x 4" wide x 18" long. This dimensionally stable tool steel is ideal for manufacturing precision tools, fixtures, gauges, and machine components where accuracy and durability are critical.

Key Features:

• AISI O1 oil hardening tool steel for excellent wear resistance and edge retention
• Precision ground to tight tolerances for minimal stock removal
• Dimensionally stable material minimizes warping during heat treatment
• Suitable for intricate work including thin sections with minimal risk of cracking
• Can be hardened to RC 57-64 when properly heat treated
• Excellent machinability in annealed condition

O1 tool steel is a versatile, general-purpose tool steel that combines good wear resistance with toughness. It is commonly used for cutting tools, punches, dies, gauges, and precision machine components. The material is supplied in the annealed condition and can be machined, then oil quenched for hardening.
