AISI A2 Tool Steel – Properties, Applications & India’s Leading Supplier

Introduction to AISI A2 Tool Steel

AISI A2 Tool Steel — often referred to as A2 Steel — is one of the most popular air-hardening, cold work tool steels in the world. Known for its exceptional wear resistance, high hardness, dimensional stability during heat treatment, and moderate machinability, AISI A2 is a go-to choice for manufacturing precision tools, molds, and dies.

At Milano Special Steel, we are proud to be a leading AISI A2 Tool Steel supplier in India, delivering premium-quality plates, sheets, bars, and custom-cut pieces to customers across industries — from plastic mold manufacturing to automotive component production.

We stock and supply A2 Tool Steel that meets international standards, ensuring guaranteed chemical composition, perfect hardness range, and superior surface finish — all at competitive prices.

What is AISI A2 Tool Steel?

AISI A2 Tool Steel is a high-carbon, high-chromium, air-hardening tool steel. It belongs to the A-series tool steel family under the ASTM A681 specification. Unlike oil-hardening steels (like O1), A2 steel hardens in still air, which reduces distortion and ensures high dimensional stability. This makes it a preferred choice for high-precision tools.

Key Benefits of AISI A2:

• Excellent Wear Resistance – Handles abrasive environments and extended tool life.

• Air-Hardening Advantage – Minimal distortion after heat treatment.

• Good Machinability – Easier to machine in annealed condition.

• High Toughness – Resists chipping and cracking under heavy loads.

• Excellent Dimensional Stability – Maintains shape and size during heat treatment.

Chemical Composition of AISI A2 Tool Steel

The performance of A2 Steel comes from its optimized alloy composition.

This balanced composition gives A2 tool steel its combination of hardness, toughness, and wear resistance.

Heat Treatment of AISI A2 Tool Steel

Proper heat treatment is critical for maximizing steel performance.

1. Annealing

• Heat uniformly to 845°C – 885°C

• Hold for 2–4 hours

• Furnace cool at 10°C/hr down to 650°C, then air cool

2. Stress Relieving

• Heat to 600°C – 650°C after rough machining

• Hold for 2 hours, air cool

3. Hardening

• Preheat to 790°C – 815°C, then to 960°C – 980°C

• Hold and air-cool (or positive pressure quench)

4. Tempering

• Immediately temper after quenching

• Typical temper range: 150°C – 540°C

• Double tempering recommended
