2. Chromium steel-The upgrade version of carbon steels, heat treatment after the hardness of HRC 48~54, is an entry style, the use of high stability, but also pay attention to dimensional accuracy, but the face of professional users can not fully meet the needs.

3. Chromium vanadium steel-because of the characteristics of the material, has been able to meet the needs of professional users, heat treatment after the hardness of HRC 52~56, this kind of products pay attention to ergonomic design and meet international standards.
