Oxidizing inhibitors may be used to retard crack propagation for high strength low alloy steels. For D6AC the use of such inhibitors gives promise of being able to avoid hydrogen embrittlement. The critical stress intensity factor KIscc apparently may also be manipulated by use of oxidizing inhibitors. Preliminary data on multifunctional inhibitors indicate that combinations of cathodic and anodic types is more effective than the common anodic inhibitors such as chromate Hydrazine and the related nitrite ion are more effective inhibitors than chromate for steel in the presence of chlorides.
