Is phosphatation possible on stainless steels 3

[davidmoul]

Hi everybody,

it is certainly a dummy question, but as far as I can't find the answer, I'm asking:

Is it possible to apply phosphating treatment on stainless steels, and more precisely on 17-4PH steel?

Many thanks,

David

Phosphate coatings do not really work for steels with high Cr content (Cr > 5%). Oxalate coatings are used to coat stainless steels when subsequent metal forming is required. Dry film lubricants based on MoS₂ and copper plating (with or without subsequent lubricant) are also used.
