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
A2 Tool Steel Shapes
Alro stocks A2 Tool Steel in Flats, Bars, and Round Rod
Properties
A2 Tool Steel is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.
