OLARRA has developed a new technology to improve the machinability of stainless steel. Whilst maintaining both chemical analysis and mechanical properties, the structure of the abrasive inclusions is modified by the addition of Calcium, which transforms the inclusion into a softer, more globular form, which will allow a higher cutting speed and an improvement on tool life.
