Conventional stamping can process almost any material, provided the die steel has sufficient strength and the press offers adequate force.However, materials for fine blanking require specific properties:



High plasticity, low yield-to-strength ratio, and high elongation to effectively transmit compressive stresses between material crystals and suppress cracking.Uniform microstructure: Materials with uneven structures struggle to achieve consistent deformation under constant pressure.



Common Materials

Low-carbon steels: DC03, DC04, etc.

High-strength low-alloy (HSLA) steels: H420LA, S500MC, etc.

Quenched and tempered steels: 16MnCr, 42CrMo4, etc.

By adhering to these guidelines, fine blanking achieves superior edge quality and dimensional accuracy compared to conventional stamping, making it ideal for precision components in industries like automotive and electronics.
