Quick corrosion cracking test methods for high strength strainlen steels

For tests to be carried out rapidly within 10 hours) when developing new grades of steel, the following solution is indicated: ammonium hyposulfite, sodium chloride, sulfuric acid, a temperature of 50°. Steels such as 08Kh15N5D2T, 07Kh16N6, 20Kh13, 40Kh13, 13Kh15N4AMg and others can be tested in boiling sulfuric acid solutions mixed with copper sulfate and magnesium chloride. It is good practice to test steels of the 13Kh11N2V2MF kind in the mixture of magnesium chloride and sodium hyposulfite at 65°C. Findings are listed for steels 08Kh15N5D2Tu and 11Kh11N2V2MF (EI962).
