A-2 Tool Steel - High Vanadium Steel

AISI A2 Tool Steel is an air-hardening grade of steel that contains 5% chromium. A2 is noted for its good toughness and excellent dimensional stability in heat treatment. These characteristics make it a versatile tool steel that combines good performance and price. A2 Steel falls between oil-hardening and D2 high-carbon, high chromium tool steels.

Characteristics of A2 Tool Steel:

Very Good Non-Deforming
Deep Hardening
High Dimensional Stability After Hardening and Tempering
Good Machinability
High Compression Strength
