At this time, it is already late October, and it is close to late autumn in November, and winter is just around the corner. *With* Dream *Small* Say .lā

Located below the equator line, less than 1,000 kilometers away, the temperature in the Koro Kingdom still maintains more than 20 degrees Celsius during the day, and there are few industries here, so even if the living environment is put on the world, it has its unique advantages.

Universal Corporate Headquarters, Deputy General Office!

It's been a week since I came back, half-lying on the sofa, holding the bewitching stunner Mina, who has been "straightened" by the "basic" and ruddy face in her arms, unconsciously playing with two balls of silky soft flesh with both hands, and looking at the sunset outside the window.

The orange sunset is not dazzling, not irritable, and beautiful, but the pupils of the torture wind are not focused, and they are very scattered.

He's thinking about things, a tricky thing!

In the morning, Mario called, and the entire Somali Marine Corps was very satisfied with the shipment.

The first batch of orders, with an excess of 2,000 tactical AKs, has been finalized, and the transaction time will be one month later.

Hearing this, Xing Feng should have been very satisfied and happy, but reality told him that this world was not as simple as he imagined.

Davis and his group of "giveaway" workers, as well as the entire production line of small arms, have been transported to Dima Island by covert means.

Now Davis is following Mu Tianfang to set up a temporary production workshop on the island to deal with the upcoming arms "trade order".

With the production equipment and professionals, the temporary production workshop can be completed in three days and enter the standard production stage.

But the problem is in the material!

The steel used for conventional weapons used to make firearms is different from ordinary steel, and it is also different from ordinary special steel.

"Steel for conventional weapons" is a general term for alloy structural steel used in the manufacture of weapons, such as guns, cannons, tanks, and tactical missiles, and the main components.

It can also be called "weapons-grade alloy steel"!

Modern conventional weapons are characterized by high power and good flexibility, and the technical requirements for guns and artillery steel depend on their firing parameters.

Such as the jaw pressure of the artillery, the muzzle velocity of the shell, the firing speed of the bullet, the explosion parameters of the range shell (such as the effective number of explosives, the velocity of the explosives, etc.).

In the case of steel for tanks and tactical missiles, it depends on the dead weight of the weapon, as well as the time it takes to move from one place to another.

For the design and manufacture of various types of conventional weapons, the steel used for the main components must meet the relevant technical requirements.

Although the standards of alloy steel used in modern manufacturing of firearms vary from country to country, in order to ensure the hardenability of steel and improve the toughness of steel, they are inseparable from the metal additives of nickel-chromium-molybdenum-vanadium series.

Xingfeng needs to make AK for this order, and the steel of the gun body is still good, the requirements are much lower, and it is not difficult to get a suitable "alloy steel".

But what is the most important thing about a gun, besides the design process?

There is no doubt that it is the "barrel"!

Steel used in gun barrels and thick-walled large-caliber guns is subjected to complex stresses when firing.

For example, it can withstand the firing parameters of several hundred meters per second; The effect and impact of high temperature, high pressure and high-speed gunpowder gas on the pipe wall, the extrusion of the bullet on the pipe wall, the formation of high-strength tangential stress, etc.

In addition, as the bullet continues to be fired, the surface of the tube body will alternately undergo a cycle of rapid heating to more than 700 degrees Celsius, and then rapid cooling to below 10 degrees Celsius.

In this process, the structural structure of the steel produces repeated phase transitions between "austenite" and "martensite", resulting in large microstress and thermal gradients.

One can imagine how important the quality of steel is in order to withstand this process.

To take the simplest example......

An AK47 assault rifle that fires up to about 400 rounds of ammunition will have its barrel heated to a reddish "critical" state.

How do you cool him down to normal?

It's very simple, just put it in the water and soak it, without any complicated equipment.

It's simple, it's brutal, and it doesn't affect the material!

The water-cooled "Maxim heavy machine gun" is used in this way.

If it is ordinary steel, directly use water to reduce the temperature? It turns out that it will give you a big "surprise"!

There is still a long way to go after the criminal wind, and word of mouth is very important, although shoddy can fool the past, but that is not the character of the criminal wind.

In his heart, whether it is a battlefield or a shopping mall, there will always be only one purpose-

Either you don't do it, or you have to do it to do your best!

This is true even if the current party is just a group of pirates who have been attacked by the international community.

Quiet time always flies exceptionally fast.

Half an hour passed, and the focus of Xingfeng's pupils gradually condensed, and he looked at Maggie, who was sitting opposite and operating the computer.

"Little Wildcat, have you found a suitable supplier?" There was anticipation in Xingfeng's tone.

"Nope."

Maggie shook his head and said helplessly: "The alloy steel needed for the production of weapons belongs to the restricted goods of various countries, and small quantities can still be provided, and it will be troublesome to reach the tonnage level." ”

"How?" Xingfeng's brows furrowed.

"The production capacity that is willing to be provided is insufficient, and the producers who have this ability need various legal documents issued by the local country to allow production, transportation and export to foreign countries, but our company can ......"

Maggie rubbed her slightly sour fingers helplessly, "It seems that there are no formal procedures for an international arms company, and now it is an illegal enterprise, and you are the owner of a black workshop, giggle." ”

After saying this, Maggie couldn't help but laugh!

"Uh......" Xingfeng was speechless.

The military weapons company is not something you can do if you want to, even if it has a good relationship with Said.

After all, he is only a big chief, not the head of a country, and in this sensitive period, he has no way to take over this kind of company with its own sensitive buff.

Moreover, Xingfeng doesn't want to owe favors to others, so as not to be entangled too deeply in the future and affect the development of his company!

"Well, it looks like this road is not going to work."

The facts are in front of him, and Xing Feng can only reluctantly accept it and choose to take another feasible path.

"Leprechaun." Xingfeng kissed Mina's red lips, "With your identity as an informant, it shouldn't be difficult to find some material dealers." ”

"Of course, there's nothing wrong with that." Mina, with the confidence of her own profession, got up from Xingfeng's arms and walked to the other side.

"In this day and age, it's really hard to do something, if only I had my own mining area."

Davis was the owner of the mine, and later came to the steel mill himself, developed the alloy steel process of weapon quality, and finally established the "Davis Arms Company".

Refining weapons-grade alloy steel was a breeze for him.

It's a pity that not only does Xingfeng not have a suitable mining area, but also a steel mill, and for him at this stage, he wants to produce light weapons in one stop.

It's hard, it's very hard, there's still a long way to go!
