Die casting die steel is a kind of die material used in manufacturing die casting die. Its quality will directly affect the quality of die casting die. Therefore, in order to meet some properties, die-casting die steel must go through the corresponding treatment, such as heat treatment, nitriding treatment, surface treatment and so on. Do you know the function of nitriding die steel?

氮化：

Nitriding:

压铸模具钢材的氮化指在一定温度下一定介质中使氮原子渗入工件表层的一种化学热处理工艺。氮化热处理一般温度大概700度左右提高型腔型芯及运动件的表面硬度及耐磨性，防腐烛性。当然，这种温度一般都是需要根据使用的压铸模具钢材钢材而定的。目前，压铸模具钢材的氮化方法主要包括有气体氮化、离子氮化、液体软氮化三种。

Nitriding of die casting die steel is a kind of chemical heat treatment process which makes nitrogen atoms penetrate into the surface of the workpiece in a certain medium at a certain temperature. Nitriding heat treatment temperature is about 700 degrees to improve the surface hardness, wear resistance and corrosion resistance of cavity, core and moving parts. Of course, this temperature is generally required according to the use of die casting die steel. At present, the nitriding methods of die casting die steel mainly include gas nitriding, ion nitriding and liquid soft nitriding.

压铸模具钢材氮化的作用：

Nitriding function of die casting die steel:

1、能提高模具的使用寿命

1. It can improve the service life of the mould

2、增加压铸模具钢材的耐磨性、表面硬度、疲劳极限和抗蚀能力。

2. Increase the wear resistance, surface hardness, fatigue limit and corrosion resistance of die casting die steel.

3、可以提高模具表面的硬度、耐磨性、抗咬合性、抗腐蚀性能和抗疲劳性能。

3. It can improve the hardness, wear resistance, anti bite, anti-corrosion and anti fatigue properties of die surface.

以上所介绍的内容，就是压铸模具钢材氮化的作用。但是由于工艺不正确或操作不当，往往会造成模具渗氮硬度低、深度浅、硬度不均匀、表面有氧化色、渗氮层不致密、表面出现网状和针状氮化物等缺陷，严重影响了模具使用寿命。因此，压铸模具钢材氮化时要严格执行渗氮工艺规则及操作规程，严把每道工序的质量关，如发生模具氮化缺陷要认真分析其原因，找出的方法。

The content introduced above is the function of nitriding die-casting die steel. However, due to the incorrect process or improper operation, the mold nitriding hardness is low, the depth is shallow, the hardness is not uniform, the surface has oxidation color, the nitriding layer is not dense, the surface appears network and needle nitride and other defects, which seriously affect the service life of the mold. Therefore, when nitriding die-casting die steel, it is necessary to strictly implement the nitriding process rules and operating procedures, strictly control the quality of each process, and seriously analyze the causes of mold nitriding defects and find out the solutions.
