Nitrogen Diluted Endogas System

Improve annealing line operation with nitrogen diluted endogas

Endothermic gas generators provide little flexibility to tailor the atmosphere for the highest quality results. However, endothermic gas can be blended with nitrogen to adjust the atmosphere composition based on the specific carbon steel alloy being treated. For example, it may be desirable to reduce the dewpoint of the endo thus increasing the reducing potential for a brighter finish. Alternatively, the carbon potential of the atmosphere can range from neutral to carburizing based on the material being treated to range.

Benefits of Using Nitrogen Diluted Endogas

Reduced variations and spread in physical properties

Improved microstructural homogeneity and less surface decarburization
