A2 steel is an air-quenched die steel with deep air-quenched hardening properties, which is extremely beneficial for complex molds that must maintain their shape after quenching and tempering. The deformation of this steel due to air quenching is only about 1/4 of that of manganese-containing oil-quenched tool steel. The wear resistance is between manganese and high-carbon and high-chromium tool steels. Its toughness is better than any one, especially It is suitable for tools that require good wear resistance and special toughness. It is widely used in blanking dies and forming dies, rolls, punches, calendering dies and thread rolling dies, and also used in some types of scissors blades. . Cold work die steel is A2 steel imported from the United States, and it is the most widely used type of A-type air-quenched steel. It is suitable for cold work die steel that requires both wear resistance and toughness. It can replace CrWMn and 9Mn2V steel to make medium and small cold blanking dies, blanking dies, forming dies and punches.

A2 is a high-carbon, medium-chromium, micro-deformed air-quenched die steel and alloy tool steel. The steel has a medium alloy content. Because it contains molybdenum and vanadium, it has good air-quenching performance, small air-quenching size deformation, uniform carbide distribution, a certain impact toughness and relatively good wear resistance.
The steel has good hardenability, which is extremely beneficial for complex molds that must maintain their shape after quenching and tempering. The deformation of this steel due to air quenching is only about 1/4 of that of manganese oil-quenched tool steels, and its resistance is between manganese and high-carbon high-chromium tool steels. Its toughness is excellent, and it is better than O2 and D3. .
The spheroidizing annealing temperature of the steel is 820 ~ 860℃; the quenching temperature should not exceed 950°C while ensuring that more carbon and alloying elements are dissolved in the austenite; the quenching cooling method should be oil cooling.
