  • Three-step treatment of stainless steels having metastable austenitic and martensitic phases to increase resistance to chloride corrosion
    Patent number: 4495002
    Abstract: This is a process for producing improved chloride corrosion resistance in turbine components fabricated from stainless steels which contains generally at least 1% of both a martensitic and metastable austenitic phase and comprises an initial high-intensity shot peening, followed by an aging cycle at about 980.degree.-1020.degree. F. for 1/4-4 hours and a final (lower intensity) shot peening.A relatively homogeneous surface of aged martensite is produced and selective attack which forms sharp pit-like defects which initiate cracks is avoided.
