Mould design: explanation of stamping materials

Commonly used stamping materials are ordinary carbon structural steel plates, such as Q195, Q235, etc. Electrical silicon steel plates, such as: DT1, DT2. High-quality carbon structural steel plate, the chemical composition and mechanical properties of this steel plate are guaranteed. Among them, low-carbon steel is used more frequently. The frequently used grades are: 08, 08F, 10, 20..., the stamping performance and welding performance are better, and it is suitable for making punches with little force. Pieces. Low-alloy structural steel plates, commonly used models are: Q345 (16Mn), Q295 (09Mn2). It is suitable for manufacturing important stamping parts with strength requirements. Stainless steel plates are commonly used: 1Cr18Ni9Ti, 1Cr13, etc., which are suitable for stamping and processing parts with anti-corrosion and anti-rust requirements. Non-ferrous metals, such as copper and copper alloys (such as brass), are available in T1, T2, H62, H68, etc. Plasticity, electrical conductivity and thermal conductivity are all good. There are also aluminum and aluminum alloys. The commonly used grades are L2, L3, LF21, LY12, etc., which have good plasticity, small deformation resistance and light weight. Non-metallic materials, such as bakelite, rubber, plastic board, etc. The shape of precision stamping materials is most often used for thin sheets, and coils of special specifications for mass production and processing. Special block materials can be used, which are more suitable for single-piece small batch production and stamping of expensive non-ferrous metals.
