A nation's industrial development begins with junior engineers.

After some discussion, the elderly people reached a consensus.

But figuring out how to reward the little one has become a major challenge.

Not counting what the little brats made at the steel mill, there was the transistor computer, "Big Firecracker No. 1," and the discovery of that large net hidden underwater.

It seems like everyone could get a first prize, or rather, if we're going by the relevant evaluation criteria, a grand prize wouldn't be out of the question.

"Oh dear, this is difficult. Boss, could you give me a solution?"

"Haha, what's so difficult about that? The bonuses must be paid out, the medals must be awarded, one by one, nothing can be missed!"

He definitely deserves a commendation! He should be given the full recognition he deserves. Also, I'll treat him to meat during the Lunar New Year!

Unexpectedly, Old Li from the old lair raised a different opinion.

"Anything else is fine, but forget about issuing a report. I'm too busy trying to cover it up! Two comrades even went out to sea for him. If it weren't for Comrade Yucheng, my good soldiers might have been crab food..."

……

What is that little brat that everyone's been talking about doing?

I'm currently putting myself through a tough time.

Because he plunged headlong into the endless abyss of "materials".

Originally, after assisting Factory 112 in improving the J-6's manufacturing process and exchanging technical information with a research institute regarding the "Big Cannon No. 1" project, Jiangxia's trip to Northeast China could have come to an end.

Isn't this because we wanted to wait for Old Wang to go back together?

But after waiting and waiting, no one showed up. So the little guy decided to give himself a break and enjoy some activities like reindeer-drawn sleds.

Following a secret order from Minister Huang of the Third Ministry of Machine Building, Xiong Da was even assigned to tasks such as ice-breaking and fish-catching.

There are so many activities there, it's even more fun than what you'd find at the Ice and Snow World.

If it weren't for the blueprints his master brought through someone, and the help call from Director Fan of the former water pump factory, which calmed the kid down, he would have definitely gone wild.

The blueprints issue is easy to resolve; the scanner can be used in one trip.

Unsurprisingly, the large red X pronounced the extension design a failure. When it comes to mechanics, no matter how much you cry and plead, if it's not working, it's not working. Even if you think a design is ingenious, if it doesn't meet the usage requirements, it's worthless.

But what Director Fan said was a bit baffling.

It turns out that the factory had already begun trial production of 5MN hydraulic free forging.

After all, only with this thing could the large components of Project 301 and the reaction vessels and other things needed by the Ministry of Petroleum be manufactured.

Everything else is fine, but the piston cylinder and hydraulic cylinder malfunctioned.

To put it bluntly, the materials used to make these two components were substandard.

After making a piston cylinder, a single-unit test was conducted, and the cylinder body immediately and unexpectedly burst open.

The hydraulic cylinder is in a similar state; as the cylinder explodes, it also bends quite carelessly!

Oh dear, this won't do. Jiang Xia really wants to get the excavator out there.

Even if we don't mention the Third Front construction a few years later, even if it were completed now, it would allow the Workers' Stadium, which is still in the excavation stage, to be completed sooner, wouldn't it?

Even excluding excavators, Project 301 still involves a considerable amount of hydraulic equipment. Especially the deep hole boring machine we promised Professor Zhu and his team; without it, we couldn't get anything done.

What material is most suitable for the cylinder block?

Without even thinking, I can tell you the model number right now: 30CrMnSi steel. As for the hydraulic column, isn't it made of 27SiMn steel?

Isn't it obvious at a glance?

Having a ball is one thing, but figuring out how to make it is the important thing.

Recalling his metallurgical knowledge from his previous life, Jiang Xia felt a headache coming on. He was lucky to remember 30CrMnSi, and he even remembered that 30 represented a carbon content between 0.28% and 0.34%. As for the contents of the other elements, who knew? He wasn't a metallurgist.

In later generations, alloy steel grades have reached nearly ten thousand; who can remember so many?

However, if you can recite GB/T3077-2024 from memory, you'll be invincible.

Engineer Jiang Xia could simply change his name to the God of Metallurgy.

Jiang Xia recalled the last time the machine spirit descended and really wanted Lao Wang to do the previous operation again. Maybe if he got dizzy, the Alloy God would also descend.

Unfortunately, Lao Wang isn't here, so this somewhat outrageous plan seems impossible to implement, but even a fool has his ways.

If that doesn't work, then let's try them one by one. Since we know the main elements, we can just add them in little by little!

If I'm lucky, I'll always run into Schrödinger's cat!

Materials science and such are all about getting lucky.

Of course, the steel mill wouldn't play that game with Jiangxia, nor would it have a small electric furnace for him to experiment with.

But Jiangxia has scanners!

I discovered the idea of ​​scanning basic chemical bonds when I was making "Happy Sheep" in Jiangxia, but I never had time to play with it.

This function requires a physical entity, unlike mechanical structural drawings where parts can be generated and assembled based on drawings before determining where the problem lies.

Moreover, this kind of analysis is quite resource-intensive, and the scanner will only display red or green boxes depending on the element.

But where is this?

Northeast China! And it's a place that still has the original recipe for "Kexing" (a type of Chinese dish).

With this guarantee, the little brat could finally beckon to the metallurgical master: Come here!

The supporting facilities here, belonging to this industrial giant, are arguably the most complete in the country. He managed to find a chemical analytical balance with a minimum graduation value of at least 0.01 mg, and he even shamelessly begged some high-purity analytical reagents such as Cr, Mn, and Si from Anshan Iron and Steel Group.

Next, we'll just add it little by little. We need to determine the chemical composition of the alloy structural steel first so we can tailor the approach and establish a proper process flow.

Thankfully, the original recipes from Northeast China supported the little one's exhaustive experiment.

Finally, just when Jiangxia's retina was about to be marked with red spots from the analysis errors, a touch of green appeared.

未命名低强度合金钢：碳（C）0.27～0.34%、硅（Si）0.90～1.20%、锰（Mn）0.80～1.10%、铬（Cr）0.80～1.10%。

Is it done?

woohoo~~

Materials science is such a rip-off, I want to switch majors!

That's bullshit! This is only one type. The most important one, GH2747, hasn't even been tested yet!

The little brat couldn't take it anymore, so the poor man in the leather jacket was called in again to act as an experimental assistant.

However, compared to reading, the two men in leather jackets did an excellent job adding trace amounts of reagent; their hands were incredibly steady.

The test tube doesn't even shake when you pick it up!

And so, when Old Wang appeared before the little brat, reeking of fish,

The exhaustive search for materials for the little one has finally come to an end.

……

"Want a three-foot-long lobster?"

Old Wang waved the large block of ice in his hand, showing off his achievement to the little brat.

"Would you like a six-foot-long cannon barrel? One shot and all living beings are equal!"

The little brat, who had lost even more weight, held up the big tube in his hand and winked at Old Wang.
