Summary
Can anyone here tell me which of these two materials would have a greater resistance to wear?
Can anyone here tell me which of these two materials would have a greater resistance to wear? I understand that higher carbon content generates greater hardness, which provides relatively higher wear resistance. And alloying can increase wear resistance -- but I'm not sure how to directly compare these two particular materials.

Any insights you can offer are sincerely appreciated.

Can you be more specific? Alloy what with what?

My bit of research indicates that typically nickle and chromium alloying elements can increase wear resistance (in addition to general carbon content). Basically, any atom of a different size than the general lattice causes the lattice to resist movement, thereby producing hardness/wear resistance.

I think, based on carbon content alone (.80% vs .08%) the 1075 steel will exceed the stainless in wear resistance. Just looking for other insights/opinions. Thanks!

Annealed 304 would have poor gall resistance, and higher carbon steel would have greater resistance. Add chromium is typically done for corrosion resistance, and nickel for toughness and austenitic stability.

Consider that in some applications, fracture-critical members must possess high- strength, corrosion resistance and galling resistance.

Some high nitrogen steels are gall resistant.

One must consider the operating environment when selecting an alloy.
