Process Performance Measures of Mould Steel Cr12

Abstract:

As one of the popular material used in the mould industry, Cr12 is always used as cold working steel. Although Cr12 has excellent hardenability, the hardened depth is definite.During the mould manufacturing, the following phenomena have always been met: the mould blank cracks in the forging process; capillary crack appears when the mould is still in its initial service stage which can lead to the mould discarding; tool heavily wear out or tool tipping in the rough cutting mould blank after preheat treatment. In the light of these problems,analysis of forging properties, heat treatment process performance and cutting performance of the mold steel Cr12 is done and the corresponding solutions is put forward in the manufacturing in order to keep mould quality, reduce reject rate, improve mould life and optimize process performance totally.Favorite application results were obtained and they can give guidance in the mould industry.
