News on China's scientific and technological development.

this level of ignorance from Chinese netizens actually from a reputable source is shocking for me.. but if you regularly use Weibo and other Chinese social media platform. then you feel this is a daily routine. almost everyone downgrade China's achievement and the irony is, these lazy people don't even check regular updates and news from company just like we do on this forum. majority of these people still stuck in 2000-2010.

i can bet on that, cute orca didn't read about YongCheng New Materials, Guangwei and Zhongfu Shenying latest announcements.



let me tell you one more thing, these people like ''Cute orca'' are highly trusted source when it comes to PLA and weaponry. but Composite Material comes under civilian category and we have much information available in public.

I wish people would stop taking everything cute orca said at face value. Just because they’re some people in the right rooms to get some juicy gossip doesn’t mean they always have good judgment about a subject. Half of what cute orca says is unreliable because he doesn't exercise care when examining information. This includes military topics. I wouldn’t rate him as highly trusted.

super steel for fusion reactor:

Scientists Developed ‘Super Steel’ That Could Take Fusion to the Next Level​

To make fusion reactors, we need materials that can withstand its punishing environment, and a new Chinese-made material can survive reactors’ intense conditions.


Here’s what you’ll learn when you read this story:

  • The central solenoid is the heart of a fusion reactor, and a "jacket" of meticulously crafted stainless steel—capable of withstanding extreme temperatures and magnetic fields—protects it.
  • Chinese scientists say that a new super steel, called China high-strength low-temperature steel No. 1, (CHSN01), can operate at a maximum of 20 Tesla, which outperforms the steel jacket that will be used by ITER.
  • China is incorporating CHSN01 into its Burning Plasma Experiment Superconducting Tokamak (BEST) and will likely play a role in future fusion projects well into the future.

Can the recipe for the steel be tweaked to make the hot section of an engine turbine?
technically yes.. the hot section of a turbofan engine does utilize steel, but often in the form of high-temperature steel alloys. but because of the lighter weight, titanium and nickel-based superalloys are the preferable choices.

-------------------------------------------------------------------------------------------------------------------------------------
The actual information is -

Shanghai Electric has overcome six world-class forging process challenges and produced the world's first set of high-temperature gas-cooled reactor nuclear island main equipment forgings. This marks China as the only country in the world capable of manufacturing the full range of forgings for a 600MW high-temperature gas-cooled reactor nuclear island. The relevant technology has been applied to the world's first 600MW high-temperature gas-cooled reactor nuclear power unit..

6 Core technologies have pushed the boundaries of forging.

1. Ultra-large double-vacuum steel ingot reverse segregation control technology.

2. Integrated head near-net-shape forging technology. This technology enables the integral forging of a 4.8-meter head with 50 thick-walled flange interfaces, achieving an 81% material utilization rate and a 65% reduction in construction time compared to traditional segmented welding processes.

3. Cr-Mo steel microstructure and property control technology. Through 37 rounds of quenching curve optimization, the forgings were optimized to simultaneously meet 600°C high-temperature strength and -40°C impact toughness, breaking through the material performance contradictions.

The remaining three undisclosed technologies cover the entire supply chain, including smelting and heat treatment, and are supported by 15 patents.

btw, this doesn't mean what he shares is completely off, but just don't treat them as gospel.

In this case, there are some concerns that domestic producers of T700/800 CF need to overcome still, just as any new entrants need to overcome concerns of perspective customers. Just don't write doom posts like "China is screwed because these issues will never get addressed". I get really annoyed when people doom for no reason.

I'm not a huge fan of these articles from SCMP tbh. They take certain discoveries and over hype them. I trust the stuff posted on Chinese websites a lot more.
