I wish someone like Columbus/Reynolds/Tange could catch on this. It'd be awesome a road bike made of fancy/extra durable stainless steel tubing, lugged, horizontal top tube and that classic geometry but with disc brakes and thru axles.
Why though? Cr-Mo steel tubing is already superior to 304 stainless in every relevant measure, except surface corrosion. In particular this article discusses fatigue behavior, and Cr-Mo has a (much) higher fatigue limit than 304.
This is also true WRT knife steels. Old, simple carbon based steels are much stronger than most stainless steels. They tend to bend rather than chip or break (when abused). They do rust and do have less edge retention than some stainless steels (such as S90V), but otherwise they are generally stronger.
That's just not true, though. Stainless (e.g. AEB-L) is up to four times tougher than simple low-alloy carbon steel (e.g. 1095). See

High hardness simple carbon steels do have their place in knives, but what you're saying is factually incorrect.
