Improved salt bath nitrogenating method for corrosion-resistant iron material and iron units

The present invention relates to an improved salt bath nitrogenating method for the iron group materials with resistance to corrosion and the iron group units. In the improved salt bath nitrogenating process, wearability or fatigue strength is conferred on the treated iron group material by the nitr...
