| 简介 |
The present invention refers to tool steel superior abrasion resistance and elongation, produced by using the same manufacturing method thereof and relates to tool a high speed. High degree of hardness and cutting force required to a high-speed tool steel well, resistance to wear, and the generally wide range use alloy steel of the present invention, which can be used iron river tool, an optional metal and to melt the olivine by produced by, rare of olivine within the metal component and earth component are reacted is enabled which is present. Therefore, due to with these reactions, river tool of the present invention the occurrence of minute the tissue as casting same is rolling and or forging is is synthesized by the same. |
