Hi shu60,
Part size is around 50mm. It sits in a larger stainless steel 304 part, but has to engage with a non-stainless steel counterpart. Hardness of this counter part is around 30HRC. Some limited sliding between these parts can occur. No surface coatings, and practically no lubrication...

What would be a good alternative?
17-4PH with a H1050 HT, or 420 or 431...
