Did not know that. They sure seemed better to me , and looked better too.
It's an on-going issue on many mechanical groups. Many will not accept it until an aircraft tech weighs in to point out that it's illegal to use stainless on aircraft aluminum.
Many scope mounts and rings are alumimum/alloy so a good anti-seize should protect you. I wouldn't use torque values for Grade 5 (US) or higher or metric Property class 4.8.
When I was in the mechanical trades, we hated stainless because they are weaker and softer than steel, and if heated they can turn harder than glass.
If one needs to drill stainless, use lots of lube and turn the bit slowly to avoid spot heating and hardening.
Carbide bits often don't like stainless because it's soft and the bits can dig in and break.
Many vehicle manufacturers like to use stainless as exhaust manifold bolts and studs. Talk to a Cummins Diesel truck tech. When they discovered carbide bits, like Garr, their world changed as the broken studs were incredibly difficult to drill out. Ford too.
Another potential issue for stainless is that the metalurgy is often unspecified so one often doesn't know what one is buying, unless buying a known brand like Papcom Docap, Bowman, etc.
If you are interested, PM and I can send some information that we used to provide to college mechanical trades students.
