Location: So. Cal | Very doubtful, for a couple of reasons.
1. It required a lengthy heat treatment to make - that translates directly into $$. As a result, car companies moved away from this material & method after the war, once nodular iron was invented; which just required the addition of other alloying elements without the expensive heat treatment.
2. It was a GM product, so other companies have a strong incentive to develop their own, better methods to avoid having to pay their competition.
3. I believe that axles can't be cast and must be forged in order to be strong enough to take the torque. GM used armasteel to make connecting rods & other parts in the old days, to save forging costs, but it wasn't a good tradeoff, as it made those critical parts excessively heavy. Forged connecting rods create a much lighter & better product. |
