Starrett 54627 A2 Tool Steel Flat Stock 1/4" x 4" x 18"

The Starrett 54627 is a precision-ground flat stock made from AISI A2 tool steel, measuring 1/4" thick x 4" wide x 18" long. This air-hardening steel is ideal for making custom tooling, dies, punches, and precision components that require exceptional durability and edge retention.

Material Properties:

• AISI A2 tool steel with 5% chromium content for superior performance
• Air-hardening steel can be heat treated without quenching in oil or water
• High wear and abrasion resistance extends tool life in demanding applications
• Excellent dimensional stability during heat treatment minimizes warping
• Precision-ground flat stock ready for machining and fabrication

Applications:

• Custom cutting tools, blanking dies, and forming punches
• Precision gauges and measuring fixtures
• Wear plates and guide components
• Machine tool components requiring high hardness

A2 tool steel is one of the most popular air-hardening grades, offering an excellent balance of toughness, wear resistance, and machinability in the annealed condition. The precision-ground surface finish ensures consistent dimensions for accurate machining results.
