AUSTENITIC STAINLESS STEEL

摘要

The present invention provides an austenitic stainless steel having excellent resistance to high-temperature corrosion and thermal fatigue cracking, which contains, in terms of mass%, 15.0-23.0% Cr and 6.0-20.0% Ni, and the surface layer part of which has been coated with a high-energy-density processed layer having an average thickness of 5-30 µm.
