Starrett 54089 AISI 01 Oil Hardening Tool Steel Flat Stock 1/4" x 1/4" x 18"

The Starrett 54089 is a precision-ground flat stock made from AISI 01 oil hardening tool steel, measuring 1/4" thick x 1/4" wide x 18" long. This high-quality tool steel is designed for applications requiring dimensional stability and precision machining.

Key Features:

• AISI 01 oil hardening tool steel composition for superior hardness and wear resistance
• Dimensionally stable material maintains precise tolerances during heat treatment
• Ideal for intricate work and thin sections with minimal risk of cracking
• Precision-ground flat stock for consistent dimensions
• 18-inch length provides ample material for multiple projects

AISI 01 tool steel is an excellent choice for making punches, dies, gauges, cutting tools, and other precision tooling where dimensional accuracy is critical. The oil hardening properties allow for controlled hardening with minimal distortion, making it particularly well-suited for detailed work and components with thin cross-sections.
