A2 Steel Composition: Chemical Elements and Performance Meaning A2 tool steel is an air-hardening cold-work tool steel with about 0.95\u20131.05% carbon, 4.75\u20135.50% chromium, 0.90\u20131.40% molybdenum, and a small amount of vanadium. This composition gives A2 useful wear resistance, good toughness, deep hardenability, and low heat-treatment distortion. This makes A2 suitable for cold-work tools that need
