Chapter 694. Z-Steel Raw Stone
Han Sen was given many different options of gifts to consider off the Qin family. Eventually, he settled on Z-Steel raw stones.
The Z-Steel ore always had a lot of contaminants inside it. A thousand grams of Z-Steel ore could be refined to provide only five grams of pure Z-Steel metal.
The Z-Steel that was refined was really hard, but very brittle. Its fragility and stern rigidity rendered it almost unusable as a weapon or electrical component.
Refined Z-Steel was more akin to delicate porcelain than metal. It had to be combined with other metals to provide a decent weapon of fair toughness and hardness.
But inside the Z-Steel ore, there was a high concentration of rough Z-Steel. It was unknown how these Z-Steel raw stones were created, but they were a little bigger than a man's thumb. Inside them was 50% Z-Steel. Some were even higher, though, and could reach 90%.
The Z-Steel raw stones were not only really hard, but also really flexible. They were suitable for weaponry that way. When the raw stones were refined, however, they would end up very brittle. Thus, they could only be ground; they couldn't be melted down and forged into a weapon.
These raw stones were often made into bullets, but guns could not be used in a shelter, so the Z-Steel raw stones had no use there.
But the Qin family owned many Z-Steel mines. They had a lot of Z-Steel raw stones, large ones in particular.
The best batch of raw stones provided a concentration of 90% Z-Steel. They were bigger than ordinary Z-Steel raw stones, as well, and they could be ground into something simple.
