Chapter 695： Z steel rough (1/2)

The Qin family also prepared several sets of plans for Hansen to choose. Finally, Hansen chose a set of weapons polished by the original steel.

The ore of z steel generally contains a large amount of impurities. Generally, 1000 g of z steel ore can extract about 5 grams of z steel which is purely above ninety-nine.

Moreover, the extracted z steel itself is very hard, but it is very brittle, and its toughness and ductility are very poor, and it can hardly be used as a weapon or a mechanical component.

With an inappropriate metaphor, the extracted steel is like a harder porcelain. Only when it is blended with other metals, will it have good hardness and toughness, which is suitable for casting weapons.

However, in the z steel mine, there are often some high-purity rough stones. These rough stones are not known for what reason. Generally, they only have finger size, z steel content is more than 50%, and a few or even higher. Can reach ** ten percent.

These z steel rough stones are not only extremely hard, but also have high toughness and ductility. They are very suitable for making weapons, but once they are smelted, they will be as crisp as ordinary z steel, so they can only be slightly added. There is no way to really use it for casting.

These rough stones are generally used to grind bullets, but because the firearms can't be used in shelters, such z-stones are generally of little use in shelters.

However, there are many z-steel mines in the Qin family. They have accumulated a lot of z-steel roughs, and some of them have larger z-steel roughs.

One of the best raw stones, z steel content is more than 90%, and a lot larger than the average z steel rough, can be ground to some simple things.

When Hansen saw the original steel of Z steel, he thought of his own peacock shackles. Those z steels were also up to one foot long. The thick ones were like fingers. The knives were too thin, and they wanted It is not an easy task to grind out the original steel of z steel.

In Hansen's view, those rough stones are a very good arrow, as long as they are processed a little. This is very useful for Hansen.

So Hansen finally chose the batch of Z steel rough stone, and Qin family promised to help him make the arrow, just because grinding the steel is a very complicated job, it takes a long time, so Hansen he still takes Less than z steel arrow.

According to Qin’s prediction, Hansen should be able to get the first two arrows in half a month, and the Qin family will deliver two arrows every month.

Hansen is also able to understand that the original steel of z steel is hard and incapable of using chemical methods or heat treatment. It can only be slowly ground and it takes a long time.

For the Z steel arrow, Hansen is still very much looking forward to it. The steel steel arrow made from the original stone with more than 90% of the z steel content may not be worse than the crow feather arrow, and may even be stronger.

The most important thing is that the crow feather arrows can't bring shelter, but these z steel arrows can be taken anywhere.

Quietly returned to the goddess sanctuary, took the Worm Knight back, Hansen returned to the Union to check the information, hoping to find some of the whereabouts of the second generation of super-god.

”Man, did you sign up for this battle of God?” Tang Zhenliu contacted Han Sen, and asked with some excitement.

”No, it's a waste of time.” Hansen smiled.
