Tool steel plate A2 is a type of air-hardening steel that is commonly used in the production of cutting tools, dies, and punches. It is known for its excellent toughness, wear resistance, and dimensional stability.

A2 tool steel plate contains about 1% carbon and 5% chromium, which give it good hardness, wear resistance, and dimensional stability. It is an air-hardening steel, which means that it is hardened by cooling it in air instead of quenching it in oil or water.

Tool steel plate A2 is often used in applications that require high levels of wear resistance and toughness, such as blanking and forming dies, cutting tools, gauges, knives, and punches. It is also commonly used in applications that require good dimensional stability, such as high-precision molds and tooling.

When working with A2 tool steel plate, it is important to use proper safety precautions, including eye and ear protection, as well as gloves and other protective gear, as the steel can be quite hard and brittle. It is also important to keep the steel cool during machining and to use appropriate cutting tools and lubricants to prevent damage to the steel and the tools.

To maintain the optimal performance of A2 tool steel plate, it should be annealed after machining or grinding to prevent cracking and distortion. The steel can also be hardened by heating it to a specific temperature and then cooling it in air.
