... in grease (Lox-Safe). It became apparent that the presence of aluminum accelerated the stress-corrosion cracking of the stainless. Aluminum is anodic to stainless in the galvanic series — it can be used as the sacrificial anode in restricting the corrosion of the steel. In fact, the 7075-T6 alloy has...

As can be seen in Table 1 the AISI 304 and 316 potentials, in the passive state, are respectively 0,08 V and 0,05 V negative with respect to saturated calomel electrode. Galvanic series in moving sea water (4 m/sec...
