I think you are right. My guess would be the durability. Also note that at the time all irons were forged, not investment cast. I am not a metalurgist. But isn't Stainless Steel a lot harder than mild steel? Probably was a bear to make them. In my mind, the better players of the time probably didn't go for the Stainless.
I have heard that the reason they stopped making irons from forged stainless is that the forging dies wore out much more quickly than they did with the carbon steel.
I don't know why better players wouldn't have liked the forged stainless. The forged stainless 915s are as buttery soft as anything I've ever hit. Those are the irons Johnny Miller reworked and used when he was at his best.
A real shame IMO. I've disliked chrome plating ever since the chrome on my first set (which were Northwestern Pro Bilts, but I've seen chrome problems with top line stuff too) peeled like the wrapper off a Hershey bar.
Regarding the durability, all I can say is I see an awful lot of the Spalding forged stainless irons on Ebay and in thrift stores and nearly every one of them is in remarkable condition for its age, even if they've seen a lot of use. The carbon steel irons of the same vintage are in great shape only if they've been sitting unused for fifty years or if the owner used iron covers.
Of course, maybe that's the real reason they stopped making them. They didn't have to be replaced as often.
