A graduate student very solemnly took the information handed to them by Liu Lang, this is Liu Lang's "hard work", it is the only material, Liu Lang also said that only the most core people can get learning, they are obviously the most core people in Liu Lang's eyes, so they are happy, there is still a lot of pressure in their hearts.

"Professor, Liu Lang, don't worry, we will study hard and add glory to our Huaxia science and technology!"

Everyone immediately made up their minds.

"Ladies and gentlemen, the purpose of our Huaxia Industrial Science and Technology is to lead the national industrial science and technology, cultivate high-quality and high-skilled professionals, we are national college students, the starting point is much higher than ordinary workers, but the identity of college students does not mean that we can not work.

The Germans attach great importance to industrial workers, and their salaries are higher than those of university graduates, and our country is not as good as Germany in this regard.

Our Huaxia industrial science and technology is to let our college students join the ranks of industrial workers, with our minds, coupled with our practical ability, the future will become the leader of our country's machinery industry, of course, our Huaxia science and technology for these talents must give high wages, high treatment, the state does not give the company to give, the company does not give me personal money, in short, we have only one purpose, is to train our country's own industrial workers, so that they can manufacture cars, We want to make airplanes, and what we make by our hands will occupy the whole world market!"

Liu Lang's majestic words made the blood of the people present surge, and they couldn't help but applaud.

"Liu Lang, you said it so well, that's right, our Huaxia Industrial Science and Technology will be the first in the country, and even the first in the world!"

Xiong Huaizhi is also very excited.

In fact, the current Huaxia industrial science and technology in many aspects has the national first-class technology, such as stainless steel smelting technology, AOD furnace is a new generation of technology for China, but in Western countries AOD electric furnace has been manufactured as early as more than 30 years ago, after so many years of development, there are many new technologies have appeared, AOD electric furnace smelting stainless steel can only be regarded as a second- or third-rate product.

At present, the classification of western industrial stainless steel is very detailed and specific, and the categories can be divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, austenitic ferritic stainless steel, and precipitation hardening stainless steel.

The austenitic structure stainless steel matrix is dominated by the face-centered cubic crystal structure, the ferrite structure matrix is dominated by the body-centered cubic crystal structure, and the martensitic structure is the matrix is dominated by the body-centered cubic or cubic.

First of all, the lowest grade is 304 stainless steel, which is the stainless steel smelted by AOD electric furnace, which is the lowest grade in the West, but in China, it is still the most advanced stainless steel.

This kind of steel is one of the stainless steels with a large amount of application and the widest range of use at this stage, which is suitable for the manufacture of deep-drawing forming parts and acid pipelines, containers, structural parts, various instrument bodies, etc.

The second is 304L stainless steel, which has a significantly better corrosion resistance than 304 stainless steel, which is mainly used for corrosion-resistant equipment and components that need to be welded and cannot be solution treated, and can be used to manufacture various instrument bodies.

Then there is 304H stainless steel, which has better high-temperature performance than 304 stainless steel.

There is also 316 stainless steel, which has good resistance to reducing media and pitting corrosion, and is mainly used for pitting corrosion resistant materials.

There is also 316L stainless steel, ultra-low carbon steel, which has good corrosion resistance and is suitable for manufacturing welded parts and equipment with thick cross-section dimensions.

316H stainless steel, high temperature performance is better than 316 stainless steel.

317 stainless steel, pitting and creep resistance is better than 316L stainless steel.

321 stainless steel, titanium stabilized austenitic stainless steel, has corrosion resistance and has good high-temperature mechanical properties.

347 stainless steel can maintain good performance in acid, alkali, salt and other corrosive media, and has good welding performance, which can be used as corrosion-resistant materials and heat-resistant steel.

904L stainless steel, super complete austenitic stainless steel, excellent corrosion resistance, in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid has good corrosion resistance, at the same time has good crevice corrosion resistance and stress corrosion resistance, at atmospheric pressure resistance to any concentration, any temperature of acetic acid and formic acid and acetic acid mixed acid corrosion resistance is also very good.

440C stainless steel, martensitic stainless steel, the hardest among hardenable stainless steels and stainless steels.

17-4PH stainless steel, martensitic precipitation hardening stainless steel, has high strength, hardness and corrosion resistance, and has good corrosion resistance to the atmosphere and dilute acids or salts

Take a look, there are so many types of stainless steel alone, the difference is mainly in the proportion of materials and smelting methods, it is not easy to overcome them one by one, but if you don't overcome, the country will have shortcomings in materials, and it is not good to be subject to people.

After solving the AOD electric furnace, Huaxia Industrial Science and Technology has begun to further study stainless steel, so it has set up an alloy material research and development laboratory, which is headed by Professor Qian Chenghai of the School of Mechanical Engineering, Professor Qian Chenghai is also a well-known expert in national materials science, more than 60 years old this year, once studied in the United States, studied metal materials, and he is responsible for the scientific research work of the laboratory.

Of course, there are so many types of stainless steel, it is impossible for a laboratory to manufacture them one by one, their purpose is only to analyze the composition of these stainless steels, and how to smelt them, is to solve these problems technically, when Huaxia Industrial Technology will master these patents, as for the large-scale smelting of metals, it will be handed over to the enterprises in the market to do.

Labs develop new technologies and then companies apply them to the market, similar to Silicon Valley in the past 30 years.

Thirty years later, Silicon Valley in the United States can be said to be the forefront of the world's science and technology, those companies are like crazy to see whose technology is advanced, so that they don't care about how the technology is applied to the market, such as WeChat, which is popular in China 30 years later, its initial technology came from a little-known small company in Silicon Valley, which was invented and thrown aside, and happened to be found by Chinese companies to buy it for a small amount of money。

There are also mobile payment software, mobile taxi software, and mobile food ordering software, all of which were invented by companies in Silicon Valley, and were also just invented and forgotten by their inventors, and then bought by entrepreneurs at a low price to make a lot of money.

This phenomenon is very strange, in the eyes of outsiders, inventors can obviously make tens of billions or even hundreds of billions of wealth with their own inventions, but they voluntarily give up, but instead they are almost paranoid to focus all their energy on the next invention, and when the new technology is invented, they are still the same, and then challenge the deeper technology, this behavior is similar to that of fools.

Are these people really stupid? Of course not, even Liu Lang is willing to become such a person, because in the eyes of these people, money is nothing at all, just enough to eat and drink, their vision is on the future of the entire human race, and what they want to do is to lead the world's science and technology.

In other words, these people are not the ones who create money, but the people who create the future of humanity.

And Liu Lang's positioning of Huaxia Industrial Technology Co., Ltd. is like this, I may not necessarily become the richest enterprise in China, but must become a leading national science and technology, and even the world's science and technology enterprises, such a pattern, not everyone can achieve.

The further study of stainless steel is the first opportunity, the process of the Volkswagen company is the second, and then there is the transformation of machine tools, and then the research of chips, these Liu Lang and Huaxia Industrial Science and Technology will not let go, and then there will be a mechanical processing laboratory and a chip research laboratory, etc., through these laboratories to absorb talents from all over the country.

Liu Lang discovered the process of Volkswagen, the impact of this matter is still not visible, the top priority is how to manufacture the parts on the drawings, this matter is not something Liu Lang can do, even if he has extraordinary intelligence, but he can't directly change the shape of the metal by his mind, if that is the case, he will not be called Liu Lang, but renamed "Magneto".
