Within the core category of cold work tool steels, AISI A2 and D2 are widely used in industrial applications. In the AISI classification system, A2 belongs to the “air-hardening, medium-alloy” group (Group A), while D2 belongs to the “high-carbon, high-chromium” group (Group D). A2 is the mainstream air-hardening tool steel today, offering excellent hardenability, good […]

Drawing dies stretch and deform metal sheets between a punch and a die to produce a cup-shaped workpiece. Their effectiveness depends on excellent wear resistance and anti-seizure properties. In many applications, choosing the right tool steel is critical. For example, steels like D2, D3, H13, H11, 1.2379, 1.2080, 1.2343, or 1.2344 can achieve optimal performance.

Understanding the Punching Process This material mainly manufactures punches and dies for blanking and punching metal or non-metal plates. The sheet deforms between the punch and the die at the initial punching stage. As deformation increases, the sheet’s lower surface cracks due to the resulting high tensile stress. Die and punch wear gradually around the

         At present, the common cold work die steel in the world can be divided into three categories: (1) low alloy cold work die steel; (2) medium alloy cold work die steel; (3) high alloy cold work die steel. In addition, several new cold work die steels have also been developed as

Die steel, as a variety of materials to shape the “mother”, is indispensable in industrial production. They are not uniform, but according to the different working environment and needs, finely divided into three categories: Cold work die steel: As the name suggests, this type of steel is mainly used in molds at room temperature or
