Tian Yutaka and Yuuchi Uchida rushed over after receiving the news. Naohiro Iwasaki handed the test report left by Du Xiaodi to Tian Yutaka. Tian Yutaka only read a short paragraph and then sat down dejectedly:

"How is it possible that the steel composition is wrong!"

In the past few days, Tian Xiongtse and his friends have also guessed the causes of various accidents and conducted repeated verifications. However, one aspect they have not questioned, that is, the problem with the steel itself. According to the design, the base of the fractionation tower uses No. 40 chromium-molybdenum structure steel. This steel is produced by Sendo Steel in Japan and is widely used in various steel structures. Many projects in the past have also used this steel.

Sedo Steel Institute is a super-large steel company in Japan. It has a history of 90 years and is well-known in Japan and even the whole world. Tian Yutetoshi never doubted the quality of the steel produced by Sedo Steel. When he designed the structure, he calculated the structural stress completely according to the material composition and technical indicators provided by Sedo Steel. These days, he and his friends calculated the model over and over again, and all the parameters were repeatedly checked, but they never doubted the technical data of the steel.

But the report in front of me is very clear that the steel composition of the base of the fractionation tower is very different from the No. 40 chromium-molybdenum structural steel claimed by Sendo Steel. The chromium content is one-third lower, and the specific gravity of molybdenum, titanium, manganese, vanadium and other are also different, and they are all relatively low. As for what this means, Tian Xiongzhe also feels as bright as a mirror.

Compared with ordinary steel, special steels have various alloy elements contained in steel. Alloy elements are much more expensive than iron, so the higher the proportion of alloy elements, the higher the price of steel. If a steel claims to contain 1% chromium, but in fact only 0.7%, then its price is inflated, and at the same time, its various properties will inevitably not meet the specified requirements.

The most important thing is that the model of the steel and the solder used during welding must match each other. The base welding process of the fractionation tower requires the use of No. 74 welding wire because this base is made of No. 40 chromium molybdenum steel. If the proportion of various alloy elements in the steel is different from No. 40 chromium molybdenum steel, the selection of the welding wire must also be changed accordingly, otherwise the optimal welding effect cannot be achieved.

There are only two reasons for the pouring of the fractionation tower. One is that the force exceeds the design strength of the base, and the other is that the strength of the base does not meet the design requirements. These days, Tian Xiongzhe and others have done a lot of calculations to determine that under greater wind conditions, the force of the fractionation tower base will not be higher than the design strength, so the reason can only be checked from the latter one.

The weld cracking under the base under stress conditions indicates that the strength of the weld is insufficient. Tian Xiongzhe also suspected that the worker had operated incorrectly or used the wrong welding wire, but he never expected that the problem was that the steel composition was incorrect. The chromium-molybdenum steel with the promised No. 40 chromium-molybdenum steel was not sufficient.

Tian Xiongzhe was also troubled by this problem for many days, and all kinds of data were engraved in his mind. When he looked at the analysis report, he realized that the report was real because it perfectly explained the problems he encountered. If calculated based on the data on the report, the result would be completely consistent with reality.

"Is it because the steel was used wrong?" Yuuchi asked.

"This is impossible. All steel plates have marks printed on them, and they need to be checked before cutting." Naohiro Iwasaki flatly denied that the base of the fractionation tower was built with material loading on the construction site. If the steel is used incorrectly, it means it is his pot.

Tian Xiongzhe also shook his head and said, "We have also considered this issue. During the investigation, we specifically checked the steel material release records, and the model was not wrong."

"So...is it a problem with the steel from the Sendo Steel Institute?" Uchida Yu's face was a little pale, which was a very horrifying guess.

"This is impossible, Sedo Steel Manufacturing Institute... how could such a mistake be made?" Naohiro Iwasaki also thought that Uchida Yu's guess was too bizarre. Who doesn't know that Sedo Steel Manufacturing Institute is a golden signboard in Japan, and the Sedo logo on the steel is almost a guarantee of quality. Anyone who works in Japan would rather suspect that the rice balls he ate for lunch were actually not rice but dough dumplings, and would never doubt that Sedo's steel would have quality problems.

"So, is there something wrong with this report?" Yuuchi Uchida said again. "Maybe the Chinese just took a fake report to cheat us, with the purpose of letting us clarify for them."

Tian Xiongzhe also said: "This is impossible. It is very easy for us to do a test. Just go to the site to get some samples..., let's do it, first, I'll ask the assistant to test the steel composition and see the results. If there is really something wrong with Sengo's steel, then... that's a big deal."

At the same time, in a hotel in Perot City, Du Xiaodi was reporting to Feng Xiaochen about his negotiations with Naohiro Iwasaki. Feng Xiaochen arrived hurriedly yesterday. Du Xiaodi took the newspapers he had sued Naohiro Iwasaki, and he translated them and handed them to Du Xiaodi.

It turned out that after Du Xiaodi and Wang Ruidong left the capital, Feng Xiaochen received a report from the diplomatic department, saying that local Mexican newspapers were slandering the level of Chinese technical workers. After Feng Xiaochen saw the fax of these newspapers, he realized that his guess had come true, and the Japanese were indeed framing the blame. Later, Du Xiaodi, who had arrived in Mexico, called and reported nervously that he found that the steel used by the Japanese was not in line with the components of the steel, and I wonder if he made a mistake when he was doing the test.

"Haha, it's right if you can't match it!" Feng Xiaochen laughed on the phone. In this era, the whole world believed in Japanese myths. Who would have thought that so many scandals of Japanese companies would break out in more than 20 years later? According to the situation disclosed in later generations, the fraud of the steel data of Sendo Steel has been happening for several years at this time. However, under its reputation, no one would question this aspect. In other words, the experienced Du Xiaodi was able to guess the differences in the steel composition based on a slight subtle color difference, so he found a place to conduct inspections. If someone else had thought of this?

"You mean, there is really something wrong with Sendo steel?" Du Xiaodi was shocked when she heard Feng Xiaochen's words. She was in the electric welding industry and had trained in Japan. She was naturally very familiar with the daimyo of Sendo Steel Making Institute. Nowadays, when "Made in Japan" is at its peak, she asked her to suspect that there is something wrong with Japanese steel, which really subverts her three views.

"I believe in your test results. This time the problem is indeed a steel problem!" Feng Xiaochen said.

"Okay, I'll inform them about this."

"Not busy..." Feng Xiaochen's mind flashed and he quickly ordered: "Xiaodi, don't make a statement first, wait until I go over."

"What? Come here?"

"Yes, this is an opportunity. It would be a pity if you don't seize this opportunity!"

Feng Xiaochen left as soon as he said that he had obtained a visa urgently through the relationship between the Ministry of Foreign Affairs and also transferred to Mexico through the United States. After arriving in Perro City, he managed to find the newspapers that slandered Chinese workers a few days ago, translated the relevant contents on it, and handed it over to Du Xiaodi, giving her instructions like this, and then waited in the hotel to watch the good show later. Of course, at the end of this scene, he, the director, wanted to make a guest appearance.

"Xiaochen, why are you sure there will be problems with Japan's steel?"

After Du Xiaodi reported the situation, she still asked Feng Xiaochen with some anxiety. She repeatedly tested the steel four or five times until it was foolproof that the test report was issued. But even so, she still felt that she might have made a mistake in some place. The reason was that how could the Japanese make mistakes?

"Why won't the Japanese make mistakes?" Feng Xiaochen asked back.

"Because..." Du Xiaodi was speechless. Isn't this an obvious thing? How meticulous the Japanese are, how dedicated the Japanese are, how devout the Japanese are... How devout when bowing.

Feng Xiaochen smiled and said, "Xiaodi, in fact, Japanese people are also humans, and they will make mistakes if they are humans. But Japanese people are different from others. That is, this country is on an island with frequent earthquakes, forming a national character that is extremely pessimistic and full of crisis. This character makes them dare not face their mistakes. Once they make mistakes, their first reaction is to conceal and then shirke them. When they can't do these things, they will escape in extreme ways."

"Well, it seems to be a bit of that."

Du Xiaodi remembered those days in Japan and felt that the Japanese around him were indeed a bit like Feng Xiaochen described.

"The Japanese economy is facing a turning point. The consequences of the Plaza Agreement are beginning to appear, and the entire Japanese society will stagnate. It is normal for widespread fraud to occur at this time. If I guess correctly, even if I realize the quality of steel, Iketani Manufacturing will choose to keep silent and not make it public. Because once the problems of the Sedo Steel Factory are exposed, the quality of the project that Iketani Manufacturing has done before will be questioned, which is not a loss they can bear." Feng Xiaochen analyzed.

Du Xiaodi said: "Then do we want to publish this report?"

"Of course it cannot be announced." Feng Xiaochen said. Seeing Du Xiaodi's surprised look, he smiled and said, "What does the Japanese do to harm the Mexicans? If we seize their handle, we have to make good use of them and squeeze out oil and water from them to the greatest extent. If the Japanese want to keep it secret, I will help them, but the hush fee must be calculated carefully."
