Abstract
Many efforts have been devoted to utilize high chromium steel turning scraps since the high chromium steel were widely used in the engineering field, but no report of great success has been heard yet owing to the difficulty to overcome the easy oxidation of chromium and picking up carbon from the residual cutting oil on the surface of turning scraps. It is essential to reduce the carbon content as low as possible to maintain good mechanical properties and machinability. The authors have carried out several experiments to find the most suitable method for cleaning the turning scrap on the point of view to keep the picked up carbon as low as possible and also gave some suggestions to utilize the products.
