6” x 24.5” A-6 Tool Steel Round Bar/Rod Stock A6 Air Hardening

AISI A6 tool steel is an air-hardening, cold work tool steel designed for applications that require good dimensional stability, wear resistance, and ease of machining. It bridges the gap between oil-hardening tool steels (like O1) and high alloy air-hardening grades (like A2).

🔹 General Characteristics

• Air-hardening – reduces distortion during heat treatment

• Good wear resistance – suitable for moderate tooling wear conditions

• High machinability – easier to machine than A2 or D2

• Excellent dimensional stability – holds size well during hardening

• Lower hardening temperature than most air-hardening steels
