wet clutch material

Hi,
I'm looking for some advice on a wet clutch material for a limited slip differential. I've found it hard to find much useful information on metal/metal clutch materials.

My knowledge of materials is very basic but looking at a couple of other clutch packs i've seen some very basic metal/metal multi plate setups that look to be nothing more than stamped spring steel. The driven/drive disc appear to be made of the same material in some I have physically seen, but the dana ones posted below have some slight color difference?

Some suggestions have been hot rolled c1045, 65mn/1066. I've heard also heard nitriding would help prevent galling?

Any advice on material would be greatly appreciated. I'm also thinking of placing some holes or angled slots in one or both of the plates to aid in oil circulation, but would be interested in any suggestions.
