I think a lot of non-road use steel, so I think still available, depending on crank standard. My aftermarket 50/34 double was supposed to come with aluminum rings, showed up with steel, I wrote polite WTF letter to amazon seller, pointing out the ad said aluminum rings. No problem, no need to get amazon involved, we'll send you aluminum rings. Took a month from China and through their Nevada distributer or customs agent, but they arrived. And they promptly changed their amazon ad to reflect the actual material. No longer sold on amazon, but same crank is on ebay, choice of steel (cheaper) or aluminum (only about $8 more if I recall). So steel is still around. I didn't want the weight of steel, but they turned out to be a lot thinner than cheap-bike steel cranks, and have held up well.
