In the following days, Europe and the United States, island countries, stick countries, etc. are all hopeful, hoping that the steel produced by Galaxy Iron and Steel Company is only useless.

After all, the data of the steel electric arc furnace is data, and after all, it depends on the quality of the steel produced!

Most of the month passed quietly.

It has been three days since the first batch of high-quality steel produced by Galaxy Steel.

Shenshi, Mechanical Metal Testing Center.

More than a dozen inspectors in white scientific clothes are sorting out the data in their hands.

"This high-quality alloy steel produced by Galaxy Iron and Steel Company is really too high-quality!" Dr. Wang Dalei said in shock as he looked at the detected data in his hand.

After the inspection of this alloy steel, the following data was obtained.

Carbon content: less than 009. It is important to know that the carbon content of general alloy steel generally does not exceed 020. The high carbon content will also reduce the steel's ability to resist atmospheric corrosion, and high-carbon steel in the open yard is prone to corrosion.

Phosphorus content: less than 0018. In general, phosphorus is a harmful element in steel, which increases the cold brittleness of steel, makes the welding performance worse, reduces the plasticity, and makes the cold bending performance worse. Therefore, the phosphorus content in the steel is usually less than 0045, and the high-quality steel is even lower. Now the phosphorus content of Yinhe's alloy steel is lower than 0018, which is already better than the international level.

Sulfur content: less than 0019. Sulfur is also a harmful element in general. It makes the steel produce hot brittleness, reduces the ductility and toughness of the steel, and causes cracks during forging and rolling. Sulfur is also not good for welding performance, reducing corrosion resistance. Therefore, the sulfur content is usually required to be less than 0055, and the high-quality steel is required to be less than 0040. The addition of sulfur from 008-020 to the steel can improve machinability, often referred to as free-cutting steel.

"Shhh...... I have to say that this alloy steel has indeed reached the level of the top of the ball. It's even surpassed!"

"Yes, with such steel, we in China no longer need to ask Europe, the United States, and island countries to import them. Hmph, now we can produce it ourselves. Thanks to the Galaxy Group, it has saved our steel industry in China. ”

Several doctors are full of emotion, and at the same time, they are also enthusiastic. There is also a deep sense of pride.

"In addition to alloy steel, the following steels are also very good, such as carbon structural steel, tool steel, ......"

"That's right, take this high-quality carbon structural steel as an example, this data is also the leading parameter of the ball. One tester said excitedly.

They all know that the carbon content of carbon steel is about 005~070, and some can be as high as 090. It can be divided into two categories: ordinary carbon structural steel and high-quality carbon structural steel. The former contains more impurities, low price, used in places with low performance requirements, its carbon content is mostly below 00, manganese content is not more than 080, the strength is low, but the plasticity, toughness, cold deformation performance is good.

Except for a few cases, it is generally not heat treated and used directly. It is mostly made of strip steel, special-shaped steel, steel plate, etc. It is mainly used in railways, bridges, and various construction projects to manufacture various metal components that bear static loads and mechanical parts and general weldments that do not require heat treatment. High-quality carbon structural steel is pure, with few impurities, good mechanical properties, and can be used after heat treatment. According to the manganese content, it was divided into two groups: ordinary manganese content (less than 080) and higher manganese content (080~120). The carbon content is below 025, and most of them are used directly without heat treatment, or after carburizing, carbonitriding, etc., to manufacture small and medium-sized gears, shafts, piston pins, etc.; The carbon content is 025~060, and the typical steel grades are 40, 45, 40N, 45N, etc., which are mostly quenched and tempered to manufacture various mechanical parts and fasteners; The carbon content is more than 060, such as 65, 70, 85, 65N, 70N, etc., and it is mostly used as spring steel.

All of the above are ordinary carbon steels, however, high-quality carbon structural steel has a lower content of sulfur, phosphorus and other non-metallic inclusions than ordinary carbon structural steel.

According to the different carbon content and use, this kind of steel is roughly divided into three categories: 1 less than 025 is low carbon steel, especially 08F, 08Al with carbon content less than 010, etc., which is widely used as deep drawing parts such as automobiles and cans because of its good deep drawing and weldability...... Wait. 20g is the main material for making ordinary boilers. In addition, mild steel is also widely used as carburizing steel in the machinery manufacturing industry.

2025~060 is medium carbon steel, which is mostly used in the quenched and tempered state to make parts for the machinery manufacturing industry. 3 > 06 is high-carbon steel, which is mostly used in the manufacture of springs, gears, rolls, etc. According to the different manganese content, it can be divided into two steel groups with ordinary manganese content (025~08) and higher manganese content (07~10 and 09~12). Manganese can improve the hardenability of steel, strengthen ferrite, and improve the yield strength, tensile strength and wear resistance of steel. Usually the grade of the steel with high manganese content is marked with "N", such as 15N, 20N, to distinguish it from carbon steel with normal manganese content.

"At present, the carbon steel produced by Yinhe Iron and Steel Company is better than the above high-quality carbon steel data! It is simply more than ten times the gap ......."

Soon, these tests were transmitted back to Galaxy Steel from the various test centers.

That's right, the steel produced by Galaxy Iron and Steel Company was not only sent to a testing center for testing, but a total of five places. Two places in the country and three places abroad.

After the five testing centers were tested, the ministry finally sent the test reports over.

Then, Galaxy Steel Company released these test reports.

At the same time, official websites, websites, etc. have been announced, and those testing centers have admitted it on the Internet.

All the same steel!

As soon as the news came out, it shocked the ball!

"Hahaha...... It is worthy of being a new, most awesome, largest, highest output, highest temperature and most scientific steel electric arc furnace. The steel produced is really the best in the world!"

"We, Huaxia, are not afraid of Europe and the United States banning the sale of steel to us. Hehe, now we can also produce it ourselves. ”

"Before, those Europeans, Americans, and island people still questioned whether our steel production was okay, but now they are slapped in the face, right? ”

"I'm going to see if they're going to cry and faint in the toilet this time. ”

…………

Countless netizens here in Huaxia are very happy, because Yinhe Iron and Steel Company has really supported the Tiantian steel industry in Huaxia. The production steel has been produced and sent for testing, and the quality is the world's top!

On the contrary, after Europe, the United States, island countries, stick countries and others saw how excellent the steel produced by the Galaxy Group was, and it was even better than theirs, they were all angry and vomited blood!

They know that their joint sanctions against the encirclement and suppression of Huaxia's iron and steel field this time can be regarded as a failure!
