I'm trying to find a steel alloy piston (gudgeon, wrist) pin that is a rating of 70 HRC (760 brinell hardness).
This steel must be able to be processed through nitriding chemical process to emphasizing the hard wearing properties of the carbon in the steel to the surface.
Steel stable nitrides include chromium, molybdenum, aluminium, vanadium, tungsten and i believe nickle is one also.
Anyone got any ideas what alloys can achieve this hardness rating with out being like glass?
PS: Nice easy question for my everyone first question on here ha. Hope everyone is well.
