What Is Steel Billet?

The steel which is made freshly, and is still in the form of a rectangle or a metal bar, is referred to as steel billet. Steel has to be processed into more useful pieces first, before its products get sold into the market. In its pure form, raw steel will not be of any use, so it must be cast into the shape.
