Sweet~~! ~~Su's gold~~! ~~Chang and Nei~~! ~~White clouds of Mongolia~~! ~~ Obo is known as China's two major non-ferrous metal smelting pillars, and a large part of the military production system is relying on these two basic pillars to establish, develop, and grow into a giant military industrial complex in later generations!

Because one of them is a veritable nickel capital, and the other is a world-renowned rare earth capital.

Needless to say, rare earths are known as the cornerstone of military materials, especially with the advent of the scientific and technological revolution, the value of rare earths is gradually highlighted, from aircraft carriers to small thumb-sized chips; From space shuttles and space stations in outer space to nuclear submarines diving deep under the sea, rare earths are inseparable from the core material.

As for the importance of nickel, although it is not as extensive as rare earths, it is the most indispensable core material for special alloy steel, because adding nickel to alloy steel can greatly improve the mechanical strength of steel, and the amount does not need to be too much, as long as the proportion is controlled between 2.94% and 7.04%, the mechanical strength of the smelted alloy steel can reach a high-quality level between 52.2 kg / square millimeter and 72.8 kg / square mm.

And such a powerful alloy steel is the most basic and the most core manufacturing material for heavy weapons and equipment such as armor steel, cannon steel, and warship steel, because of this, since World War II, nickel has become one of the national reserves of major military powers as the most important strategic resource.

And the lack of nickel reserves in the country, it is equivalent to losing the weapon to strengthen the steel, not only difficult to support the war, but even will be defeated, Na~~! ~~ The best example of this is the pure Germany, because the intensity of the war was far beyond people's imagination, so that the pre-war reserves of nickel raw materials in Germany were exhausted by the intensity of the war in less than two years.

In desperation, the Germans could only make the basic materials such as armor steel and cannon steel thicker, so as to use super thickness to make up for the loss of nickel, the basic mechanical strength of alloy steel, and this also led to the later stage of the war The German tank armor became thicker and heavier, and the weight climbed, which eventually overwhelmed the power system and the actual combat ability was very low.

It is to see the example of Germany's failure, after the war, with the United States and the Soviet Union as the core, the importance of nickel has been raised to the strategic height of the national level, and at the same time of crazy reserves of nickel ore resources, it has also begun to step up the development of nickel-containing special alloy steel, so a series of such as the United States 4034 alloy steel, the Soviet Union's 75Л alloy steel and other classic nickel-containing alloy steel were born.

It was immediately used in a series of military production fields such as tank manufacturing, artillery development, ship research and development, and even submarine construction, until the 21st century, decades later, when it was still able to use the M1 main battle tank and M109 self-propelled artillery; The T-90 main battle tank, the BMP series infantry fighting vehicle, saw the shadow of 4034 alloy steel and 75Л alloy steel.

It can be seen that this nickel-containing alloy steel is of great significance to a country's military production!

However, the sad thing is that China was considered a nickel resource-poor country until the 60s of the 20th century, but China did not pay much attention to it at that time, because China and the Soviet Union were in the honeymoon period at that time, and many military raw materials were provided by the Soviet Union, and among them was the classic 75Л nickel-containing alloy steel.

Based on this, China has produced a large number of weapons and equipment such as Jiefang brand cars, Type 59 tanks, Type 54 122mm howitzers, etc., so much so that even the fledgling nuclear industry is ready to use 75L nickel-containing alloy steel to make safety pressure shells for experimental reactors......

Unfortunately, the good times did not last long, with the prevalence of chauvinism in the Soviet Union, China and the Soviet Union turned from honeymoon to hostility, and in 1960 the Soviet Union suddenly stopped all aid without notice and withdrew all aid experts stationed in China.

Some large-scale projects are stagnant, as long as you have drawings in hand, you can take them back and ponder them, and there is hope for them to start again, but if you lack the most basic raw materials, it is no different from cutting off food, even if you have drawings, you can't do anything without materials.

And the most serious of these is the serious shortage of 75Л nickel-containing alloy steel, which directly leads to a series of weapons and equipment including 59-type tanks, new 152mm howitzers, new 57mm anti-aircraft guns, and so on.

For this reason, China has not organized relevant scientific and technological personnel to carry out the imitation of 75Л nickel-containing alloy steel, but when the scientific researchers finally measured the ratio of various metal raw materials in 75Л-containing nickel-containing alloy steel, they found that the most critical nickel is the most lacking thing in this ancient country.

In desperation, China can only explore nickel ore nationwide, and on the other hand, use the rare earth that has just been put into production as a substitute for nickel, and embark on the road of independent development of special alloy steel with difficulty and slowness......

When Bai Yi saw this history in his previous life, although his eyes were full of joy after success and the spirit of hard work, as a professional who studied the manufacture and maintenance of weapons and equipment, Bai Yi knew how vast the hardships and helplessness contained in it would be.

More importantly, many military projects had to be stalled because of such a small steel plate, and there was no suitable steel for the reactor pressure shell, so China's atomic bomb could only be transferred to theoretical research again; There was no usable armor steel, and the Type 59, which had just been mass-produced, only listened to the production line and did not return to normal until the end of the 60s.

And the biggest impact of this is the new 57mm anti-aircraft gun, because the production of high-performance alloy steel has not come up for a long time, the development and rationing of the new 57mm anti-aircraft gun can only be ranked behind the priority equipment, until the mid-70s, the output of special products has come up, and the new 57mm anti-aircraft gun has been successfully developed, but at this time the so-called new 57mm anti-aircraft gun has fallen behind before it is put into service......

There are many examples of backwardness in the service of good equipment due to the difficulty of a clever woman for a rice cook, so that many people who have experienced this period of history back then, when their gray hair is gray, will say such a helpless sentence: "If our country's special steel can keep up, we can do better!" ”

Bai Yi is not a saint, but he is a person with a conscience, he can't see the lamentations of those military experts who have done their best for the country, and he can't see that they still have irreparable regrets when they are dying.

Since he knew the nickel of Jinchang, the rare earth of Baiyun Obo, and the halving of Chinese industry by the Soviet Union in the 60s, why didn't he turn the dagger into a butcher's knife and pour out the original materials urgently needed by the Chinese military industry with the heavy bleeding of the Soviets? The idea is very bold, the method is very simple, the operation is very practical, but now it depends on how many tons of blood the Soviets who have already taken the bait......
