CLASSIFICATION OF EASY CUTTING STRUCTURAL STEEL

To improve the machinability of steels by certain elements in steel, which is suitable for the automatic machine of high speed cutting steel is easy cutting structural steel. Easy cutting structural steel although the steel containing P, S more, single in this kind of steel is as a beneficial element to join or save down, therefore, belong to high quality steel.

Easy cutting structural steel specific grades are: Y12Pb, Y12, Y15, Y15Pb, Y20, Y30, Y35, Y40Mn, Y45Ca a total of nine grades. Easy cutting structural steel points plus sulfur free cutting steel, plus sulfur free cutting steel, plus lead free cutting steel, plus calcium free cutting steel, plus sulfur carbon manganese free cutting steel and so on.
