Greetings- I recently completed a rigging job. A few months afterward, the owner showed me that one of the wire sizes used is slightly magnetic, whereas the other size is not. Both reels of wire said 316 grade stainless. Obviously one was not. Would the more ferrous(magnetic) wire be stronger, but be more likely to rust(or corrode within the fittings)? The magnetism is very slight, but definitly present. The customer and I are unsure of what to do about it. Thanks for any enlightenment.
