If a magnet sticks to it - it ain't Stainless Steel - WRONG. - There are five distinct families of SS and some of them are non-magnetic while others are magnetic .. some even can change when heated. - and some are mixed.
Way back in 1798 experimenters started working at adding chromium to iron & steel - but generally it is stated that stainless steel was invented in 1913 at the same British firm (Firths) who had been delivering "silver, spring" steels to Samuel Colt for some 20 years in the mid 1800s.
Some early stainless steel guns suffered from GALLING or cold welding of sliding surfaces - but modern lubricants and mixing the metal types has long fixed that issue.
I like shiny things ..I even like polishing stuff like copper, brass and steel - and I hate RUSTY tools
'Patina' is prized and said to be rust and damage that indicates authenticity. Hmm. - I'd say it indicates NEGLECT.
