Resistance of Ferritic Stainless Steels to Stress Corrosion Cracking


Stress corrosion cracking tests were carried out on 0.020-in.-diameter wires under dead-weight loading in boiling solutions of MgCl2, Ca(NO3)2, and NaOH. The T430 and T434 ferritic stainless steels were immune to stress corrosion cracking in MgCl2 under conditions which caused various austenitic grades to fail in 6 to 46 min. Pitting corrosion in MgCl2 reduced the cross-sectional area of the ferritic steel specimens to the extent that they could not support the load, and they failed in a ductile manner. Stressed specimens of ferritic stainless steels did not fracture in Ca(NO3)2 or NaOH even after heat treatments which led to intergranular corrosion. Corrosion potential measurements were made on the stressed specimens and correlated with various stages in the stress-corrosion cracking process.
