Chapter 419 Research and Development of Alloy Steel No. 4150

"Thank you, everyone. I am still in the stage of understanding. When the project is really launched, I will ask everyone to work together."

Chen Jianye said politely.

The two went to Su Xincheng's office.

"The formula of 4140 steel? Jianye, this is no joke. You have to sign a confidentiality agreement before I let you see the information."

Su Xincheng glanced at the two of them and tapped the table lightly with his fingers.

He was also thinking whether he should let Chen Jianye touch upon things related to the military industry.

This thing is too sensitive. If a leak occurs, the entire leadership of the steel mill will be punished.

"I agree to sign, Chief Engineer Su, let's follow the procedure."

Chen Jianye said.

"Okay, so you want to do material research and development upgrades?"

Su Xincheng asked.

"Yes, I talked with Comrade Xia Jinhui in the third workshop for a while and learned about the performance of 4140 steel. I want to try to see if I can upgrade it."

"No. 4140 steel is of military quality. If it can be upgraded, it will be a great opportunity for improvement for our unit and the military industry."

Chen Jianye told the truth.

"Your idea is very good. I can approve it for you."

Su Xincheng nodded.

Su Xincheng should take the responsibility for showing Chen Jianye the information about steel No. 4140.

Normally, it would have to go through several rounds of review, but Su Xincheng was the chief engineer of the steel rolling mill, and he had the authority to directly give Chen Jianye access.

Of course, it was also because of Chen Jianye’s outstanding performance in the past that Su Xincheng valued him and was willing to give him a chance.

Chen Jianye signed a confidentiality agreement.

Su Xincheng signed a note and handed it to Chen Jianye: "Steel No. 4140 is highly confidential, and only you can see it."

“If you want to set up a project, you can share the information within the team after it is approved.”

"Thank you, Chief Engineer Su. I understand."

Chen Jianye took the approval note.

He then went to the information room and after handing in his approval slip, the staff took out a stack of materials.

"Thank you."

Chen Jianye took the materials and went back to the technical office with Luo Renping.

"How's it going?"

"Did Chief Engineer Su agree?"

“Can the project be officially launched?”

Several engineers couldn't wait to ask.

"Why are you in such a hurry? Jianye just got the information and hasn't even started yet."

Luo Renping said unhappily.

Several engineers looked at the document bag in Chen Jianye's hand.

"No one is allowed to see it. Comrade Jianye signed a confidentiality agreement before he got the approval from Chief Engineer Su."

"If you read the contents of the document, it is a serious leak."

Luo Renping warned.

Several engineers quickly looked away.

They all knew the seriousness of the leak.

At the very least, you lose your job, and at worst, you go to jail.

There is no mercy at all and the punishment is very severe.

Chen Jianye found an office desk and checked the information of steel No. 4140.

He saw the experience of developing 4140 steel. More than ten years ago, the Ministry of Metallurgy received an order to develop stable and durable steel for use in military products.

After two months of research and development, the technicians came up with steel No. 4130.

It met the demand for high-end steel at that time.

After developing 4130 steel, technicians did not stop there.

A few years later, the formula was slightly changed and 4140 steel was introduced with further improved durability.

It marks the further enhancement of the performance of domestic steel.

4140号钢材的配比大概是1%的铬，0.25%的钼，0.4%的碳，1%的锰0.2%的硅。

Slightly less than 0.035% phosphorus and 0.04% sulfur.

The remaining 94.25% is iron.

The data on paper was very simple, but the technicians who were developing the steel at the time exhausted all their efforts.

'The proportions seem to be similar to the high-strength steel I remember, the only difference is the carbon content.'

Chen Jianye pondered in his heart.

Carbon content is the most obvious indicator of different steel types.

Secondly, see whether other alloys are added to the steel.

Steel like 4140 is a typical high-strength alloy steel.

"It is not easy to add carbon to alloy steel. After changing the composition, whether the new material is stable and durable requires repeated experiments."

"But I have a recipe in my mind, and it is perfect for this project."

Chen Jianye made a decision quickly.

The research and development project of new alloy steel materials was launched.

He will lead the team to develop 4150 alloy steel which is stronger, more durable, wear-resistant, cold-resistant and heat-resistant.

When the bell rang for the end of get off work, Chen Jianye returned the information to the information room and rode his bike home.

After dinner, Chen Jianye accompanied Ran Qiuye for a walk, still thinking about the new alloy steel.

"What are you thinking about?"

Ran Qiuye asked.

"things related to work."

Chen Jianye smiled slightly.

After the two returned home, Chen Jianye sat at the dining table and took out his notebook to write and draw.

He wrote down the formula for 4140 steel and wrote his own modified formula below the formula.

He had the formula for the new alloy steel in his mind, but the times were different and the production processes were different, so he couldn't copy it.

The alloy steel materials that could be mass-produced after the millennium may not necessarily be produced now.

There was a huge gap between the steelmaking level, technology, and production capacity in the 1960s and those two thousand years later.

'The main thing to change is the carbon content, so start by adding 0.1% carbon content and find the most stable formula ratio.'

Chen Jianye murmured and made a decision.

He began to draft the report.

The name is 'Research and Development of New Alloy Steel Materials'.

An hour and a half later, Chen Jianye put down his pen and let out a breath.

He has written down his ideas, project establishment, and research methods.

Just submit it to Su Xincheng for review tomorrow.

Ran Qiuye had fallen asleep.

Chen Jianye lay on the bed, holding Ran Qiuye's hand, and fell asleep quickly.

The next day.

Su Xincheng's office.

"Chief Engineer Su, this is a new idea of ​​mine. Please correct me."

Chen Jianye handed over the written report materials.

"So fast?"

Su Xincheng was stunned, took the materials and started reading them immediately.

If the materials were handed in by someone else, Su Xincheng would put them on the desk and ask him to go back and wait.

Chen Jianye is different.

Su Xincheng paid special attention to him.

Anyone who works in technology knows that innovative thinking must come from young people.

For example, famous mathematicians and physicists all proposed conjectures or arguments that shocked the world when they were in their twenties or thirties.

After they are in their forties, they have basically lost their creativity and can only add bricks and tiles to the theories they proposed when they were young.

Basically, 99% of technical experts have great success when they are young, and only a very small number of people can achieve success late in life.

Even those scientists who achieved success late in life were not really late bloomers. They just did not have the conditions to complete the conjectures they had when they were young.

Young people have the most active minds and often have sudden ideas.

As we get older, our thinking becomes rigid and we are bound by traditional technical theories, so we accumulate more experience.

A few minutes later, Su Xincheng saw the research and development ideas for No. 4150 steel and couldn't help but look up at Chen Jianye.

It was hard for him to imagine what was going on in the mind of the young man in front of him.

Why do these novel and imaginative ideas come into being one after another like ripe winter melons?

Chen Jianye looked calm as he waited for Su Xincheng's final decision.

After spending about fifteen minutes, Su Xincheng put down the material page in his hand and looked at Chen Jianye again: "Comrade Jianye, your talent amazes me."
