Starrett 54221 AISI 01 Tool Steel Flat Stock 1" x 6" x 18"

The Starrett 54221 is a precision flat stock made from AISI 01 oil hardening tool steel, measuring 1 inch thick by 6 inches wide by 18 inches long. This high-quality tool steel is ideal for precision toolmaking, jigs, fixtures, gauges, and machine components requiring excellent dimensional stability.

Key Features:

• AISI 01 oil hardening tool steel for superior wear resistance and edge retention
• Dimensionally stable material maintains precision through heat treating
• Excellent for intricate work including thin sections with minimal cracking risk
• Precision ground flat stock with tight tolerances
• 1" x 6" x 18" dimensions provide versatile material for various applications
• Can be hardened to 60-64 HRC for maximum hardness and wear resistance

AISI 01 tool steel is a shallow hardening, oil quenching steel that machines easily in the annealed condition and exhibits minimal distortion during heat treatment. This makes it the preferred choice for precision tools, punches, dies, and other applications where dimensional accuracy is critical.
