Will the toughness value of die steel be standardized? Die steel is more and more widely used in manufacturing and smelting industry. With the rapid development of science and technology, the market prospect of die steel becomes better and better. There are more and more mold steel manufacturers in the market, which also makes the purity and toughness of mold steel. Today, let's talk about die steel. Will the toughness value of die steel be standardized.

模具钢材为什么对韧性值有要求？

Why does die steel require toughness value?

在工作过程中，各种模具承受着不同的冲击载荷，为了减少在使用过程中的出现折断、崩刃等形式的损坏的频率，就需要模具钢材具有一定的韧性。

In the working process, various molds bear different impact loads. In order to reduce the frequency of damage in the form of fracture and edge collapse in the process of use, it is necessary for the die steel to have a certain toughness.

韧性这个字眼在模具从业人员的嘴边常常挂起，所以它也是模材提供者比较注意的问题，一直在天成模具就业的技术员辛建东先生在台湾装备技术展上是这样解释的：模具钢的化学成分、晶粒度、纯净度、碳化物和夹杂物等的数量、形貌、尺寸大小及分布情况，以及模具钢的热处理制度和热处理后得到的金相组织等因素都对钢的韧性带来很大的影响，尤其是钢的纯净度和热加工变形情况对于其横向韧性的影响更为明显。还特别强调钢的韧性、强度和耐磨性往往是互矛盾的，要合理地选择钢的化学成分并且

The word toughness is often mentioned by mold practitioners, so it is also a problem that mold material suppliers pay more attention to. Mr. Xin Jiandong, a senior technician who has been employed in Tiancheng mold, explained this at the Taiwan equipment technology exhibition: the chemical composition, crystal size, purity, quantity, morphology, size and distribution of carbide and inclusions of mold steel, And the heat treatment system of die steel and the metallographic structure obtained after heat treatment have a great impact on the toughness of steel, especially the purity of steel and hot working deformation have a more obvious impact on its transverse toughness. It is also emphasized that the toughness, strength and wear resistance of steel are often contradictory, and the chemical composition of steel should be reasonably selected

采用合理的精炼、热加工和热处理工艺，以使模具材料的耐磨性、强度和韧性达到佳的配合。关于冲击韧性在材料工程学里面的解释是试样材料在一次冲击过程中试样在整个断裂过程中吸收的总能量。

Reasonable refining, hot working and heat treatment processes are adopted to achieve a good combination of wear resistance, strength and toughness of die materials. The interpretation of impact toughness in material engineering is the total energy absorbed by the specimen in the whole fracture process during one impact.
