Starrett 54731 A2 Tool Steel Flat Stock 3/8" x 2" x 18"

The Starrett 54731 is a precision-ground flat stock bar made from AISI A2 tool steel, measuring 3/8" thick x 2" wide x 18" long. This premium air-hardening steel is ideal for toolmaking, die work, precision fixtures, and custom fabrication projects requiring superior dimensional stability and wear resistance.

Key Features:

• AISI A2 tool steel with 5% chromium content for excellent wear and abrasion resistance
• Air-hardening properties allow for predictable heat treatment with minimal distortion
• Precision-ground flat stock ensures tight dimensional tolerances
• High compressive strength and toughness for demanding applications
• Suitable for punches, dies, shear blades, forming tools, and gauges
• Dimensions: 3/8" thickness x 2" width x 18" length

A2 tool steel is a versatile cold-work steel that offers an excellent balance of toughness, wear resistance, and machinability in the annealed condition. When properly heat treated, it achieves high hardness levels (58-62 HRC) while maintaining dimensional stability, making it a preferred choice for precision tooling applications.
