METHOD FOR ANALYZING STAINLESS STEEL BEARING UNDER 13 CHROMIUM FOR TENDENCY TO CORROSION CRACKING

摘要

FIELD: investigating materials. SUBSTANCE: stainless steel bearing under 13% chromium is kept in solution made up of (by g/l) MgCl₂·6H₂O 180-200 or NaCl 120-140, Na₂S₂O₃ 18-23, the balance water at a temperature of 60-65 C for 10 hours until cracks develop. EFFECT: reduced analysis duration, obviated necessity for using toxic substances. 1 tbl
