    1. A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.

      Here’s what no one is talking about.
      Here’s where xxxx matters.
      It’s not just xxxxx it’s actually yyyyyyyy.
      Same steel, same team, but now it’s super duper something something.
      .
      Fuck I love AI.

    3. They literally explain it in the article:

      Adding manganese wasn’t supposed to work, based on known corrosion science.

    4. Soo, no stunning nor unexplained. Just very cool

      >The path from the first observation to publication was not quick. The team spent nearly six years moving from the initial discovery of the unusual stainless steel to the deeper scientific explanation, then toward publication and potential industrial use.

      Ok so science daily finally read a research paper from November of 2023 and are acting like nobody knows why the steel has the corrosion resistance it does.

      https://www.sciencedirect.com/science/article/abs/pii/S1369702123002390

      It’s explained in the abstract of

      Kaiping Yu, Shihui Feng, Chao Ding, Meng Gu, Peng Yu, Mingxin Huang,
      A sequential dual-passivation strategy for designing stainless steel used above water oxidation,

      I don’t think this headline is out of pocket. I’m sure that in the fullness of time scientists will develop an explanation— of why current corrosion science is wrong, for example. But the author of this research is literally quoted saying „cannot be explained“

      >“Initially, we did not believe it because the prevailing view is that [Manganese] impairs the corrosion resistance of stainless steel. Mn-based passivation is a counter-intuitive discovery, *which cannot be explained by current knowledge* in corrosion science. However, when numerous atomic-level results were presented, we were convinced. Beyond being surprised, we cannot wait to exploit the mechanism.“

      (Emphasis added).

      “Cannot be explained” is not referring to the process and formula, it’s referring to the reason the process works.

      Cannot be explained, hmmm. Could this be the evidence of aliens Trump is trying to release?

      What amazing infomercial gadgets can we sell with this?

      Does it slice tomatoes *and* aluminum cans?

      Does it improve the golf swing?

      Will it remove bird lime?

      Can you use adhesive strips of it to make a boat?

      Can you mint commemorative coins with it?

    10. So what it looks like, is that they either coat the stainless steel in a manganese solution creating a double protection, or they mix in manganese with the chromium in isolation and mix it in to their final alloy.

    11. Several steels already exist that are extremely corrosion resistant such a H1, LC200N and Vanax SuperClean

      The HKU team’s answer was a strategy called „sequential dual-passivation.“ Instead of relying only on the usual chromium oxide barrier, SS-H2 forms a second protective layer.

      Explained

      I work in an industry where Chromium based stainless steel just barely fails to meet our performance criteria and requires expensive and very much overkill inconel.

      Seems like this material could be revolutionary

      New technology STUNS scientists — “We’re so stupid and dumb” says researchers with stars spinning around their heads.

      Oop. UAP Disclosure and now alloys are being made from materials that unexpectedley work really well together.

      It’s like, how much more stainless could this be? And the answer is none. None more stainless.

    17. So… Steel’s version of battery news of the day that will never see the light of day.

    18. ok Redditors let me help out here since so many comments are jokin about the apparent contradiction in “cannot be explained“ followed by some explaining.

      stainless or corrosion resistant steels are normally described as stainless in specific environments.

      1) cheap stainless steel spoon in your dishwasher probably won’t rust ever. unless you put it in salt water.

      2) higher quality marine grade stainless steel won’t rust in salt water. unless you rub on it like a horny teen, as it scrapes off the thin chromium oxide layer

      3) really high quality marine stainless is hardened and treated to prevent wear and wear induced corrosion .

      NONE OF THIS WORKS IF YOU RUN ELECTRICITY THROUGH IT!

      Rust and corrosion are electricity. So no they can’t fully explain yet why when running massive amounts of electricity through this new type of stainless steel, a somewhat mysterious 2nd layer of manganese oxide forms. Normally manganese weakens the chromium oxide layer. In the past some really nasty toxic chromium ions were released during electrolysis (see Erin Brokovich) which kills people and destroys the steel. Weird shit happens in electrolysis. similar to battery chemistry. It’s a really cool discovery and this type of material science while not breaking the laws of physics still doesn’t lend itself to simple explanations.

      Alright, Spyderco. You know what we want. Magnacut, Vanax, and Magnamax get out the way, there’s a new kid in town.

      If it could run at like 63-65+ and retain toughness as well…that would really make it the next big thing.

    20. Ozymandias2347 on

      I know why they can’t explain it, I bet it’s because the old Scottish engineer and his doctor friend that helped them come up with it mysteriously disappeared before they could explain the formula.

      There are likely useful applications for this SS, however sea water electrolysis is *not* one of them.

      All electrolyzers have a reverse osmosis unit to purify water before use, even if source is fresh water.

      * Energy cost to use RO to desalinate water is 0.035 kWh/kg of H2

      * Energy cost to electrolyze water is 50 kWh/kg of G2

      Using salty water for electrolysis instead of fresh increases total energy requirement by not even 0.1%. This is not an engineering challenge, this is a topic universities around the world are just wasting time on because they aren’t looking at the whole picture.
