Chen Xing has been very busy these days.

As the shopkeeper of Changan Precision, he is now devoted to researching the materials of bolts and nuts with a group of craftsmen.

At the beginning, the raw materials of Chang'an precision crafts were purchased from the iron smelting workshop or the Aniu special steel workshop in the Chu King's Mansion.

Bolts and nuts are new things, and many workshops in the workshop city have begun to be used on a large scale.

This quickly attracted a group of workshops to join this ranks.

Nowadays, there are no ten workshops that can make bolts and nuts in Chang'an City, and there are eight.

Although some are just shops like small family workshops, they can also find their own way of survival.

The workshops invested by some noble families introduced steam locomotive lathes faster than Changan Precision, which put a lot of pressure on Chen Xing.

In addition to the material cost, there is only processing cost for bolts and nuts, and the parts can be said to be relatively simple.

Those who are responsible for purchasing in workshops can roughly calculate the theoretical cost of bolts and nuts.

This has led to increasingly fierce competition among various bolt and nut workshops.

But Chen Xing didn't want to fight a price war with everyone, nor did he want his workshop products to be the same as other people's families.

It happened that during this period he found a lot of inspiration in the papers in Science, so he bought a batch of zinc ingots, chromium ingots, manganese ingots and nickel ingots from Guanshishan Academy and Fanyang Lushi Chemical Research Institute at a high price.

Then he personally led a group of capable craftsmen to conduct various experiments.

As a bolt and nut workshop, Chen Xing naturally did not build iron smelting equipment on a large scale, but the iron smelting furnace was also installed.

The purpose is to buy ordinary steel from outside and then process it into special materials yourself to make bolts and nuts.

This idea is considered by Chen Xing to be the foundation of Chang'an precision craftsmanship in the future.

Everyone can make the bolts and nuts themselves.

But whose bolts and nuts are more corrosion-resistant, have higher strength and are less likely to fail.

It depends on their respective technical content.

Obviously, Chen Xing now wants to smelve his own special steel.

"Of the shopkeeper, this group of special steels with nickel and manganese added are obviously higher than the original strength. I think the next experiment can focus on this direction and see what proportions are so that the special steel produced can perform the best."

Chen Tie just finished testing a few special steel samples and was quite excited.

As the craftsman with the highest technical level of Chang'an Precision, although Chen Tie is only a Level 6 worker, his technical level is already very high.

Before this, the quality of any kind of steel purchased by Changan Precision was not as good as this one.

"It seems that His Highness the King of Chu's previous inference is correct. Adding these newly discovered metals to other metals in an appropriate proportion will produce unexpected effects.

If we can really find special steels with super high strength, then in the future, even if our Changan Seiko bolts and nuts are twice as expensive as others, or even several times more expensive, many people will come to buy them."

As the largest bolt and nut workshop owner in Datang, Chen Xing knew very well how much the Tang Dynasty demanded bolt and nuts.

If you look at the new four-wheeled carriages and bicycles that are increasing the use of bolts and nuts, you will know that the prospects for these small things are definitely not small.

"It will definitely be successful. The quality of the steel we have now tested is much higher than before. Next, we will continue to test these strength, toughness and other properties just now according to the steel test standards announced by Guanshishan Academy.

I heard that the Iron Smelting Workshop of the King of Chu and the Steam Engine Research Institute of Guanshishan Academy have developed a equipment specially designed to test the fracture strength of steel, which has further quantitative standards for the performance of steel.

Although this device is probably not cheap, I suggest you still need to buy one.”

No one who does research does not like better experimental equipment.

Chen Tie is naturally no exception.

Many craftsmen in the Tang Dynasty have always lacked attention to the quantitative confirmation of various technologies.

Many things are plausible and unbelievable.

Guanshishan Academy and various workshops in the Chu King’s Mansion have been promoting the production of various standards.

To this end, many associations have been established to formulate standards for various industries.

Obviously, the steel test standards are one of them.

Although it has not been officially released yet, Chen Tie, who has a unique vision, has realized that the testing equipment used in the iron smelting workshop of the King of Chu Mansion will definitely be involved in the steel test standards in the future.

It is definitely a good thing for the development of Datang's steel industry to quantify and clarify information such as the breaking strength of steel.

These standards in the steel industry will ultimately have a series of impacts on various metal products.

For example, how much lateral force does a bolt break after it bears?

This actually depends on the performance of steel.

"As long as you think there is necessary equipment, buy it. If our Changan Precision Ke wants to become the largest and most professional bolt and nut workshop in Datang, related experimental equipment is naturally indispensable.

It just so happened that the workshop made a lot of money last year, but there was no dividend yet, so I just used it to invest in experimental equipment."

When you reach Chen Xing's level, you no longer have a very intuitive feeling about money.

The net worth of tens of thousands of yuan has no direct impact on living standards.

As a popular stock in the Datang Stock Exchange, even if Changan Precision has a pullback during this period, its overall market value is still very high.

Chen Xing has countless ways to solve the problem of purchasing funds for experimental equipment.

"Thank you, the shopkeeper. After the scale of our own special steel workshop will increase in the future, we will probably make a lot of money by selling special steel to the public.

I heard that many workshops in the workshop city have very unique requirements for some parts. If special steel is not used, the lifespan of those parts and the accuracy after use for a period of time will not meet the requirements.

Once our special steel is successfully mass-produced, we can immediately seize part of this market."

Chen Tie felt even happier when he heard that his shopkeeper agreed to his request.

He seemed to see a broad road coming towards him.

Maybe I can continue the invention of special steel and directly pass the seventh level worker and become the first eighth level worker in Chang'an Precision.

He was excited to think that he could personally take over the medal of the eighth-level worker from His Highness the King of Chu.

Many craftsmen in the Tang Dynasty would work hard for the eighth-level workers. In addition to the interests behind it, the medals issued by Li Kuan personally was also a very important reason.

After all, except for the workshops in the King of Chu Mansion, the craftsmen in other workshops will only have the opportunity to receive the treatment of Li Kuan personally issued medals after passing the unified craftsman assessment and becoming a level eight-level worker.
