Is Damascus steel high carbon? What is the best quenching method?

The traditional manufacturing technology of Damascus steel has been lost. Now Damascus steel can be said to be high carbon steel or high carbon alloy steel. Of course, there are also Damascus steel with high carbon and low carbon mechanical mixing. It's best to quench with oil, otherwise the sword is not tough enough and easy to break. At present, Damascus steel with sufficient toughness and high hardness is stainless steel of Sweden RWL34 and PMC. The long sword can be bent 360 degrees without breaking after heat treatment to HRC57/54.
