Steel Production

The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed. The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. The coke is cooled ...

2017-05-25 · Tool steels are a very popular choice for making knives. Tool steels are, for the most part, carbon steels that have additional alloying elements that increase their mechanical properties. These alloying elements often increase the steel's corrosion resistance as well, though not to the level of a stainless steel.
