... between 0.15 and 0.9% to determine which carbon potential was best suited to that steel. Theoretically, an endothermic carrier gas, perhaps with a slight enrichment (e.g., 0.5% C potential), should have been adequate. The tests showed that to obtain the best results the atmosphere had to be carburizing...
