CHAPTER V.
THE GENERAL EFFECT OF THE MORE
IMPORTANT ELEMENTS IN TOOL STEELS.
We know that all metals of engineering nature are crystalline in character, that is, the crystals form when the metal solidifies. If these crystals were free it would be easy to determine definitely just what properties the metal would have. However, the crystals are not free, but exist in the steel in combination with many other types of crystals. This results in many complicated and complex possibilities in the finished product, and will bring us presently to the subject of "Alloy Steels".
