Nitralloy

Nitralloy 135M是美国渗氮钢，属于ＳＡＥ７１４００，ＡＭＳ６４７０，化学成分Ｃ０．４２，ＳＩ０．３０，ＭＮ０．５５，ＣＲ１．６，　ＭＯ０．３８，　ＡＬ１．０．不太清楚对应的国产钢

里面的成分还有P为0.04 S为0.04,有人知道对应的国产钢吗

从实际出发,楼主应当选取一个在性能上达到要求的国产材料,否则材料采购肯定会有问题.
而且,从化学成份上对比也很难找到非常接近的材料.

这个材料性能要求比较高,
要求调质加渗氮以后,表层硬度应在65-67HRC,渗层为0.3-0.5,核心硬度要达到300-340BHN
就是因为达不到要求才去试着寻找相近的材料.
有人知道吗?

中国渗氮钢一般采用38CrMoAl，你可以比对一下机械性能

我们用42CrMoH代替美国的材料,热处理变形小,很实用

42CrMoH可能达不到硬度的要求,38CrMoAl氮化性能可能更好一些.

> If someone would be so kind as to offer a layman's definition of Nitralloy 135M I would appreciate it. I've googled as best I could and cannot find anything useful. I am primarily interested in its "grind-ability" properties.

Nitralloy 135 is a low-alloy steel optimized for nitriding.
Nitrifing will create a very hard but thin surface case layer.
Nitriding is useful when quenching a steel to temper it would cause
distortion or warping.

It is specified by AMS 6470 or 6472.

Nitriding process and parameters are available in AMS 2759/6.

Results from grinding will be similar to any case-hardened material.
The hard case is difficult to grind. The case is thin, so extensive
grinding will
wear through the case.

我来试翻译下。

Nitralloy 135 是为了渗氮而优化的低合金钢，Nitralloy在表面生成一层很薄但是硬度很高的保护层，当钢在进行淬火很容易发生扭转或变形，这时Nitriding的优点就非常突出了。

它的说明可以在AMS 6470 or 6472中找到。
