daminox it has always been one of the prime targets of our research to further optimize the hardening techniques for stainless steel watchcases the latest development which can be described as a small revolution is called daminox the daminox process is a surface hardening technique which diffuses great amounts of carbon into the top layers of an austenitic stainless steel alloy aisi 316l etc after a special pre-treatment the diffused carbon is very evenly spread within the matrix of the alloy causing a defined micro-tension which in return results in a huge increase of hardness and wear resistance ...
