    模具钢中什么钢材硬度高韧性好?

    来源:/ 日期:2022-06-14 发布人:admin


    什么钢材硬度高韧性好?
    What kind of steel has high hardness and good toughness?
    模具钢硬度高,一般而言是指硬度HRC50以上;韧性好,一般是指模具钢不会断裂或崩块。
    High hardness of die steel generally refers to hardness above HRC50; Good toughness generally means that the die steel will not break or collapse.
    什么钢材硬度高韧性好?
    What kind of steel has high hardness and good toughness?
    这个问题大致可以分三种情况来回答:
    This question can be answered in three ways:
    一种是硬度HRC50-58之间的,韧性好的模具钢是LG。LG模具钢硬度HRC56-58,韧性是DC53的8-9倍。
    One is the die steel with hardness between hrc50-58 and good toughness is LG. LG die steel has hardness hrc56-58 and toughness 8-9 times that of DC53.
    二种是硬度HRC58-60之间,此硬度区间抗崩裂性能好的模具钢是8566模具钢。8566模具钢硬度HRC58-60,它的抗崩裂性能是高速钢SKH-51的4倍,D2的2倍。
    The second is the hardness hrc58-60. The mold steel with good cracking resistance in this hardness range is 8566 mold steel. The hardness of 8566 die steel hrc58-60 is 4 times that of high speed steel skh-51 and 2 times that of D2.
    三种是硬度HRC60-62之间,此硬度之间韧性比较好的模具钢就比较多了,因为没有具体的实验数据,不敢说谁好,大致有DC53、LD、8566二代、88、CALDIE。
    There are three kinds of hardness: hrc60-62. There are many die steels with good toughness among these hardness. Because there is no specific experimental data, I dare not say who is better. There are roughly DC53, LD, 8566, 88 and caldie.
    论模具钢合金成分。
    On the alloy composition of die steel.
    合金成分是模具钢性能的基础,但模具钢的性能,除了跟合金成分有关,还和冶炼工艺、热处理工艺、生产厂家(也就是)有关系。
    Alloy composition is the basis for the performance of die steel, but the performance of die steel is not only related to alloy composition, but also related to smelting process, heat treatment process and manufacturer (i.e. brand).
    为了买到好的模具钢,有人强调合金成分含量(也就是模具钢型号)、强调厂家。可道高一尺魔高一丈,你只能强调看得见的东西,看不见的工艺,还是可以做手脚,降低成本,赚取差额利润。低级骗子,合金成分上做假;冶炼工艺上做假,不留痕迹,悄无声息。
    In order to buy good die steel, some people emphasize the alloy content (that is, the model of die steel) and the manufacturer. You can only emphasize what you can see and what you can't see. You can still do things to reduce costs and earn profits. A low-level liar who fakes on the alloy composition; The smelting process is fake, leaving no trace and silent.
    钢材还是那个钢材,厂家还是那个厂家,外壳还是那个外壳;可偷减冶炼工艺,比偷减合金成分挣的更多;还没人能发觉。可消费者在用的时候品质不稳定、效果达不到,消费者吃哑巴亏。道高一尺魔高一仗,骨子里面的基因,决定的做事风格。
    The steel is still the steel, the manufacturer is still the manufacturer, and the shell is still the shell; The smelting process can be stolen to earn more than the alloy composition; No one has found out yet. But when consumers are using it, the quality is unstable and the effect can not be achieved, and consumers are dumbfounded. The way is better than the devil. The genes in your bones determine your work style.
    采购模具钢,选人比选合金成分更重要。
    When purchasing die steel, it is more important to select personnel than alloy composition.
    钢材组织偏析是由于凝固或固态相变而导致的钢中化学成分的不均匀发布称为偏析。
    Steel structure segregation is the uneven release of chemical components in steel caused by solidification or solid phase transformation, which is called segregation.
    偏析分为微观偏析和宏观偏析。
    Segregation is divided into micro segregation and macro segregation.
    微观偏析是指显微组织红成分的不均匀发布,是由凝固或固态相变产生的,微观偏析一般是指枝晶偏析。
    Microsegregation refers to the uneven release of red components in microstructure, which is produced by solidification or solid phase transformation. Microsegregation generally refers to dendrite segregation.
    微观偏析可以通过高温扩散处理减轻,但枝晶偏析有效的办法是采用炉外精炼冶炼工艺,更大限度地降低钢中有害杂质(S、P,O、H、N)含量,生产纯净钢或洁净钢。
    Micro segregation can be reduced by high-temperature diffusion treatment, but the effective way to eliminate dendrite segregation is to adopt out of furnace refining and smelting process to reduce the content of harmful impurities (s, P, O, h, n) in steel to a greater extent, so as to produce pure steel or clean steel.
