Starrett 54176 AISI O1 Tool Steel Flat Stock 5/8" x 1-1/2" x 18"

The Starrett 54176 is a precision flat stock made from AISI O1 oil-hardening tool steel, measuring 5/8" thick x 1-1/2" wide x 18" long. This versatile tool steel is ideal for toolmakers, machinists, and fabricators who require dimensionally stable material for precision work.

Key Features:

• AISI O1 oil-hardening tool steel composition for superior performance
• Exceptional dimensional stability during heat treatment
• Minimal risk of cracking, even with thin sections and intricate designs
• Precision ground flat stock ready for machining
• Ideal for cutting tools, gauges, jigs, fixtures, and dies

O1 tool steel is renowned for its excellent machinability in the annealed state and superior edge-holding characteristics after hardening. This flat stock can be heat treated to achieve hardness levels between 57-62 HRC, making it perfect for applications requiring wear resistance and toughness. The oil-hardening process provides deep hardening penetration with minimal distortion, ensuring your finished parts maintain tight tolerances.
