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.

If you exclude cost as a relevant measure.

Stainless is more expensive as well

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.

Totally. Just curious why the above wanted a stainless bike. If you want a steel road bike with disc brakes and thru-axles you can absolutely order one right now. I myself ride a Soma Wolverine with Tange Prestige Cr-Mo tubing, flat mount disc brakes, and thru-axles.
If you wanted a bike that didn't necessarily need painting, you can order a bike like that in titanium tubing instead.
You think a country of 1.4 billion people is utterly incapable of metallurgy, simply because some of their products are intentionally designed as cheaply as possible, to be sold on a market that wants products sold as cheaply as possible?
Are you also an expert on 3D nano-scale material science? It sounds like you only know a couple terms about stainless steel on a macro scale.

Yeah - 304 is nasty stuff for work hardening, too. I wonder if what they're really describing is a very specific amount of work hardening that improves certain mechanical processes. It can't be hardened/tempered since it's austenitic, but maybe selective work hardening provides some benefits.
(p.s., I sure hate milling 304 parts)

That's plain racism.

There's a pervasive thought in the English speaking world that Chinese people are unable to achieve creativity and are only capable of copying western innovation.

Serious publication or not (which, BTW, is an instance of the Argument from Authority fallacy), they aren't immune to the problem of junk science.[1]
> That's plain racism.
Not the OP, but I believe the intended reading of "Chinese" in this context is "product of the present Chinese social and economic system" and has nothing to do withe race or ethnicity (e.g. it wouldn't apply to Taiwan). The present Chinese system has a significant problem with bad science.[2]

There is no intended reading that makes "Chinese metallurgy is an oxymoron" a sensible thing to post any place where you want to have a halfway reasonable conversation with strangers.

I can't access the PDF from that Springer link - what are the numbers for other countries?

I'm not sure anyone was saying they're immune to it, but their reputation does lend them credibility when compared to a random HN commenter that says stuff like "Chinese metallurgy is an oxymoron"

I don't know much about stainless, but work hardened alloy steel has benefits and isn't less reliable. For example, the rolled splines on automotive shafts.

It is sad to me that much of Asia went straight to the "publish or perish" phase of science. There once was an era when science was about pushing the edge of our understanding of nature rather than just pushing the edge of what is publishable for promotion. In the west that goal has been slowly lost (like many things it became infotainment), and some still strive for new knowledge. It's not that good research doesn't go on, it's just very product/engineering focused and business profit dominated. The majority of academic stuff everywhere that is not immediately verified is enshittified to varying degrees.
So this article still gives me both hope that it is real, and sadness that it probably isn't.

It's weird, and it's racist.
Also demonstrably wrong if you look at something like https://en.wikipedia.org/wiki/List_of_Chinese_inventions
