Automobile patent monopoly

Many people refer to C-IASI (China Insurance Research Institute) as "rim Commission for Discipline Inspection" and C-NCAP as "five-star wholesale department", but in fact this impression is not formed by the different standards adopted by C-NCAP and China Insurance Research Institute, but by the differences in test items. Domestic car companies that have long been used to "optimizing" according to the C-NCAP rules are easily "overturned" when they suddenly face the C-IASI of a brand-new test project.

One of the important differences is the frontal offset collision. Like European E-NCAP, C-NCAP adopts 40% offset collision at 64km/h and C-IASI adopts 25% offset collision at 64km/h, which is consistent with IIHS of American Highway Safety Insurance Association. In this regard, some "malicious" car companies have to make more preparations, swear and change into steel bars. After all, safety is no small matter (ensuring sales is important)!

Speaking of this, I have to mention that the 25% offset collision is very complicated, and there is a serious injury that many car manufacturers can't solve. It is necessary to use high-strength hot-formed steel to meet the safety standards, and the cost should not be too high or too difficult. ...

What most people don't know is that there is a company with monopoly technology: you need high-strength steel and thermoformed steel to build a car, and you must buy his own-ArcelorMittal, which was founded less than 20 years ago and is the only steel company in the world that can provide a full range of aluminum-silicon coated thermoformed steel.

How much money can he earn from this unique technology? General automobile high-strength steel is 5k yuan/ton, his family sells 8k, and the other 3k is a monopoly profit. The annual consumption of hot-formed steel for automobiles in the world is 300w tons, and China needs 100w tons. Come and experience it.

What are the advantages of hot-formed steel?

This has to start with the evaluation index of steel: yield strength and tensile strength. Its maximum tensile strength can reach 1K5-2K5? MPa, and the strength of a nuclear submarine. Applying it to the key parts of the car body can obviously improve the anti-collision ability and overall safety of the car body, and reduce the weight of the car body while meeting the high standard safety regulations.

Brands/models with a high proportion of hot-formed steel in the world:

Volvo XC90, the utilization rate is over 40%

Link 03, 16%

Land Rover Discovery 13%

Jeep commander, 13%

Haval H7, 1 1%

Baowo BX7, 10%

But hot-formed steel also has disadvantages:

After a traffic accident and serious deformation, the hydraulic tongs and jacks of the fire brigade cannot be disassembled at all, and they can only be cut, which may cause secondary injuries.

Why can't others do it?

Coating technology to prevent oxidation, he will, others will not. It can be compared with "True and False Gleevec" in Life and Death. Strict protection of patents and huge investment threshold will lead to "de facto monopoly", which is inevitable.

Attachment: The patent of this company will expire in 2026.

By then, we will wait and see whether the price of high-strength thermoformed steel will come down and whether more and more vehicles will successfully pass the 25% offset crash test to meet the safety standards ~
