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
wear through the case.
What else do you need to know?
No, 135 is a specific alloy w. specific composition.
Phosphorus .025 max
Sulfer .025 max
Nickel .25 max
Copper .35 max
It can be hardened by conventional methods before nitriding (AMS6472)
or nitrided as received (AMS6470)
