effective case depth of 31CrMoV9 nitriding workpiece
(OP)
what's the maximum effective case depth of 31CrMoV9 nitriding workpiece U can achieve ? 0.75mm?
In most Eu&U.S wind generator gear with nitriding ,which widespread effective case depth did u choose? 0.5MM?
thanx everyone

Not to confuse the issue but the reason I suggested the technical paper in my last post was that the wind turbine OEM gear boxes are a planetary gear design, and do not use nitriding for the planetary gears. The planetary gear set along with the low, intermediate and high speed pinion/gear sets use gas carburizing with great success.
The only time I have seen nitriding used was by one wind turbine OEM, and this was for the large ring gear.
