Starrett 54590 Precision Ground Flat Stock 1/8" x 1 1/4" x 18" A2 Tool Steel

The Starrett 54590 is a precision ground flat stock made from AISI A2 tool steel, measuring 1/8" thick x 1 1/4" wide x 18" long. This air-hardening tool steel is ideal for manufacturing cutting tools, punches, dies, and precision components that require superior wear resistance and dimensional stability.

Key Features:

• AISI A2 tool steel with 5% chromium content for enhanced performance
• Air-hardening steel composition eliminates quenching distortion
• Exceptional wear and abrasion resistance for extended tool life
• Precision ground surfaces ensure tight dimensional tolerances
• Medium alloy steel with excellent machinability in annealed condition
• Hardness range of 60-62 HRC when properly heat treated

A2 tool steel is a versatile cold work steel known for its combination of toughness and wear resistance, making it the preferred choice for applications requiring minimal dimensional change during heat treatment. The precision ground finish provides a ready-to-use surface for demanding tooling applications.
