@steven-cavagnolo @ole-olson @steve-d I believe Chrome is the metal that increases the wear characteristics of valves and reduces their magnetic feature. I remember Stellite valves as being used in truck other extreme applications.

Steve D, I don't think nickel is magnetic. Only ferris metal is magnetic. Aside from the rare steel penny from 1943(?) no American coin is magnetic. In the old days, vending machines used magnets to detect and remove fake coins.
