Kirin Coat C

This has an enormous effect on improving the lifespan of high deformation, drawing and cold punching dies.


  1. Even under usage environments in which no effect can be attained with conventional coating, the lifespan of the die can be improved.
  2. It has an effect on high deformation from the bending process, etc. of stainless steel and high tensile strength steel, and on strong impact from cold punching or other processes.
  3. It is performed as a surface preparation for special nitriding, and improved adhesiveness and lifespan by alleviating the hardness gap.
