Starrett 54421 AISI 01 Tool Steel Flat Stock 3/8" x 6" x 36"

The Starrett 54421 is a precision-ground flat stock made from AISI 01 oil-hardening tool steel, measuring 3/8" thick, 6" wide, and 36" long. This high-quality tool steel is ideal for manufacturing cutting tools, gauges, dies, and precision machine components.

Key Features:

• AISI 01 oil-hardening tool steel for superior wear resistance and edge retention
• Dimensionally stable during heat treatment, minimizing warping and distortion
• Excellent machinability in the annealed condition
• Suitable for intricate work including thin sections with minimal risk of cracking
• Can be hardened to Rockwell C 57-62 for demanding applications
• Precision ground to tight tolerances for consistent results

AISI 01 tool steel is a versatile, general-purpose tool steel that offers a balanced combination of wear resistance, toughness, and machinability. It responds well to oil quenching and is particularly well-suited for applications requiring intricate shapes, sharp edges, and minimal dimensional change during hardening.
