Starrett 54147 AISI 01 Tool Steel Flat Stock 1/2" x 1/2" x 18"

The Starrett 54147 is a precision-ground flat stock bar made from AISI 01 oil-hardening tool steel, measuring 1/2" thick x 1/2" wide x 18" long. This high-quality tool steel is ideal for fabricating custom cutting tools, precision gauges, jigs, fixtures, and specialized machining applications.

Key Features:

• AISI 01 oil-hardening tool steel for superior wear resistance and edge retention
• Dimensionally stable throughout heat treatment processes
• Excellent machinability in the annealed condition
• Minimal risk of cracking during hardening, even in thin sections and intricate work
• Precision-ground to tight tolerances for consistent dimensions
• Can be hardened to 60-64 HRC for demanding applications

AISI 01 tool steel is a versatile, non-deforming oil-hardening steel that combines good toughness with excellent wear resistance. Its stability during heat treatment makes it the preferred choice for complex shapes, fine details, and applications requiring precise dimensional control after hardening.
