锻造模具材料参考：

Forging die material reference:

1、热锻模具钢有：H13，3Cr2W8V，LG，8566。其中8566的耐高温性能好，使用硬度HRC58-60，硬度高耐磨性好。LG模具钢韧性非常好，使用硬度HRC54-56。而H13是目前国内常用的中等级别热作模具钢。

1. Hot forging die steels include: H13, 3Cr2W8V, LG, 8566. Among them, 8566 has good high temperature resistance, high hardness and good wear resistance. LG die steel has very good toughness and hardness hrc54-56. H13 is the most commonly used medium-grade hot work die steel in China.

2、冷锻模具钢有：DC53，LD，8566模具钢。

2. Cold forging die steel includes: DC53, LD, 8566 die steel.

还可以用Cr12MoV,5CrNiMo，5CrMnMo，4Cr5MoSiV1，4Cr5MoSiV等模具钢来制造冷冲模、热锻模、压铸模等模具的钢种。使用Gr12来制作锻模也是常见的，Gr12的韧性要好一些。另外制作锻模，能给模具的型腔通过热涨冷缩的方法加上套版，这样可以防止模具的开裂。

Cr12MoV, 5CrNiMo, 5CrMnMo, 4Cr5MoSiV1, 4Cr5MoSiV and other die steels can also be used to manufacture cold stamping dies, hot forging dies, die casting dies and other die steels. It is also common to use Gr12 to make forging dies. Gr12 has better toughness. In addition, when making a forging die, it is best to add a template to the die cavity through the method of heat expansion and cold contraction, so as to prevent the cracking of the die.

模具钢的磨损量，取决于接触压力，模具表面硬度，摩擦系数，冲压时的相对滑动距离和冲压生产零件总数。

The wear amount of die steel depends on the contact pressure, die surface hardness, friction coefficient, relative sliding distance during stamping and the total number of stamping parts.

模具钢的磨损程度是非常不均匀的，有些地方磨的特别厉害， 跟我们身上衣服的磨损不均匀一个道理。现在的有限元软件可以通过计算磨擦功来预测模具各处的磨损程度。聪明的模具工程师在检查计算时，可以识别出来那里是发生很大磨损的地方，然后就千方百计地避免不必有的磨损.

The wear degree of die steel is very uneven. It is particularly severe in some places, which is the same as the uneven wear of our clothes. The current finite element software can predict the wear degree of the die by calculating the friction work. When checking the calculation, a clever die engineer can identify that there is a great wear and tear, and then try his best to avoid unnecessary wear and tear
