Conclusions 1. Short-duration carbonitriding of a punching tool for clod closed-die forming made of steel R6M5 makes it possible to increase durability by a factor of 1.7 to 2.5. 2. The composition used for the working bath is more economic and less toxic compared with that used currently. 3. Additional tempering after carbonitriding makes it possible to increase toughness of the diffusion layer without reducing its hardness. An oxide layer is formed which facilitates wearing in and improves the appearance of the tool. 4. The optimum schedule for final heat treatment for punches is carbonitriding at 550±10°C for 10–20 min and tempering at 430–450°C for 30 min.
