Stainless steels galling information?

[awhicker84]

I have a A479 CL 2 base material that needs a straight dowel pin installed with standard interference. The first thought I had was to get a 304 pin due to corrosion, but I realized galling may be a problem. Is there any information regarding which stainless steels can be 'mixed' in an interference situation or is best to avoid any and all stainless on stainless interference?

Thanks much,

Andy

old references from Armco (now AK) and Carpenter have such information, they both make steels with high galling resistance.
The biggest key is hardness, think like a 17-4PH pin.
