摘要：

A new pressurized-ESR furnace was developed whose maximum nitrogen gas pressure was 5 MPa, and maximum weight of ingot was 20 kg in Fe equivalent. By using the P-ESR, a high nitrogen-bearing austenitic stainless steel with more than 1 mass% of nitrogen was successfully fabricated, its impurity was reduced to less than 20 ppm by Ca deoxidation.
