Steel 1XI8N9 welded and non-welded and at initial stretching loads above the yield value, is protected from corrosion cracking in boiling 42% MgCl/sub 2/ solution acidified by HCl (0.1% by volume, s. g. 1.19) with the aid of inhibitor PB-5 in 0.2% concentrations. The addition of 1% BA-12 inhibitor +0.04% KI to the boiling 42% MgCl/sub 2/ solution has a similar effect. The inhibitors PB-8 and BA-12 + Kl retard the corrosion cracking process of the metal in the sbove solution but do not inhibit it completely. Divalent and trivalent iron salts (0.3 mole/l) cause complete loss of protective action of PB-5 but do not affect that of BA-12. The protective action cathodic polarization and of inhibitors in the corrosion cracking of steel 1X18N9 in 42% MgCl/sub 2/ solution is additive. Anodic polarization lowers the protective action of inhibitors but does not eliminate it completely. (auth)
