On August 22, 2026, CCTV's *Xinwen Lianbo* (News Simulcast) reported a piece of news that might have escaped many people's notice: since the beginning of the year, my country has achieved major breakthroughs in seven types of high-end steel.
Seven types. It doesn't sound like a lot. But when you realize these seven types of steel span sectors such as new energy vehicles, humanoid robots, energy storage equipment, aerospace, and deep-sea equipment, you begin to grasp the significance of this achievement.
China has ranked first in the world for steel production for years-that is old news. What truly matters is what China's steel industry is doing *after* securing that top production spot.
As thin as a cicada's wing and priced by the gram: TISCO's "hand-tearable steel" sets the world record for the thinnest stainless steel.
Let's start with "cicada-wing steel," also known as "5G steel." Developed by Shougang Jingtang, it is as thin as 0.07 millimeters-roughly the thickness of a human hair and thinner than a sheet of A4 paper. Yet, it boasts both high strength and high ductility, allowing it to be easily bent or folded in half.
What does 0.07 millimeters actually mean? It means you can fold a paper airplane out of steel.
This steel has already entered stable mass production, with a daily output capacity exceeding 1,000 kilometers. Where is it used? In precision shrapnel inside mobile phones, integrated circuit substrates, signal receivers and filters for 5G base stations, connectors for new energy vehicle batteries, and even tin-plated sealing materials for high-end food packaging.

Breaking into two trillion-yuan markets-electronic information and new energy-with a single steel product is no small feat.

Next, let's talk about electrical steel. While the average person might not be familiar with it, it is a core material for the motors in new energy vehicles. The 0.1-millimeter-class non-oriented electrical steel produced by Shougang Zhixin boasts iron loss metrics that place it in the global top tier.
The data speaks for itself: this product is used by the world's top ten leading automakers, and one out of every three new energy vehicles in China uses a motor core made from it.
Shougang Zhixin's silicon steel sheets have already been used in over 3 million high-end new energy vehicles. A total of 16 electrical steel products have made their global debut.

There is also a more cutting-edge frontier: humanoid robots. Humanoid robots typically utilize dozens of motors, placing extremely high demands on materials regarding torque, weight reduction, and low energy loss-requirements that traditional materials simply cannot meet.
Shougang has developed specialized electrical steel for humanoid robots, featuring high magnetic induction and low iron loss. One particular product-an ultra-high magnetic induction, non-oriented soft magnetic material-achieves a magnetic induction intensity of 1.75T, boosts torque by 1.6%, and reduces iron loss by 27%.
The R&D process was arduous, involving over 600 formulation trials and more than ten rounds of industrial validation over the course of a full year. The product has now been validated by leading enterprises and is being supplied in stable, mass-production volumes.

Behind these breakthroughs lies a broader trend.
China's steel industry is transitioning from mere scale to true strength. In the past, discussions about the industry focused on output and volume; today, the focus is on achieving extreme thinness (such as 0.07 mm), world-class iron loss metrics, and market share among the global top ten automakers.
The entire value chain-from material formulation and rolling processes to mass production-is now independently controlled. Applications span from offshore wind power and deep-sea equipment to shipbuilding and aerospace. Newly developed low-expansion specialty steels for the aerospace sector are already being used in molding tools for large aircraft composite components. TISCO's "Extreme Environment Steel" (a type of Invar alloy for aerospace molds) boasts a thermal expansion coefficient just one-tenth that of traditional steel and is currently utilized in composite molding tools for the C919 aircraft.

Changes at the industrial level are even more noteworthy.
The downstream high-end manufacturing sector is expanding rapidly. In the first half of this year, the high-tech manufacturing sector grew by 13.3%-far outpacing the overall industrial growth rate-while industrial robot production rose by 28% year-on-year. The growth of these emerging industries has, in turn, driven demand for high-end steel. A virtuous cycle is emerging between high-end steel and emerging industries: these industries require superior materials, and those materials enable the industries to advance more quickly.
The steel industry's own digital and intelligent transformation is also accelerating. To date, three domestic steel enterprises have been designated as global "Lighthouse Factories," and a total of 36 "Excellence-level" and two "Pilot-level" smart steel factories have been cultivated.

Here are a few points worth considering.
First: When China can roll steel to a thickness of just 0.07 millimeters and produce world-class electrical steel, what becomes of the steel mills still producing ordinary rebar? The structural imbalance-characterized by an overcapacity of low-end products and a shortage of high-end ones-will only intensify amidst this technological upgrade.
Second: Material demands in emerging sectors are compelling traditional industries to upgrade. The requirements for electrical steel in humanoid robots and ultra-thin steel in new energy vehicles cannot be met simply by making minor adjustments to existing production lines. While this pressure acts as a challenge in the short term, it serves as a driving force in the long run.
Third: From "hand-tearable steel" to "cicada-wing steel," China's steel industry is building an independent materials ecosystem that spans from the ocean to the sky. Once fully established, this system will reshape the competitive landscape not only of the steel industry itself but of the entire high-end manufacturing sector.
