Cold work die steel
For example, the mold is also defective, such as ribbon and mesh carbide; process defects, such as coarse grain, surface grinding burns, rough knife marks, tempering, etc. ; Or due to improper operation of the work process overload, prone to early brittle fracture failure. Early crisp broken stainless steel mold life in Xi'an is very short, if the processing of more than thousands of pieces can easily damage its life, and some life even only a few dozen to several hundred times. Fragile fracture is flush with the same color.

Early crisp broken stainless steel mold life in Xi'an is very short, if the processing of more than thousands of pieces can easily damage its life, and some life even only a few dozen to several hundred times. Fragile fracture is flush with the same color.

There is also a part of Xi'an cold work die steel is mainly due to the cyclic stress caused by the fracture process than the brittle failure much more slowly, the mold life of 5000-10000 times or more. Fatigue fracture ports present different areas, can see the fatigue source, fatigue extension area and rapid fracture zone. Fatigue fractures are common in various heavy duty molds, such as cold extrusion die. As the heavy-duty mold in the pressure deformation process, the mold surface instantaneous temperature up to 200-300 ℃, resulting in temperature cycling, thus accelerating the fatigue crack Mengshan.
