Stupid steel question
Forgive my stupidity but my question is..
If you had a piece of mild steel that was well polished shiny etc, how do you know that it is mild steel and not stainless?
What indentifies stainless as being stainless (in terms of visual characteristics)?
Cheers
Mark
If it isn't broke, fix it until it is

Austenitic are non magnetic... Other SS grades are magnetic so not so simple...
A hot salt environment could be used an would tell you with a day or so!

as said, degrease a small patch, put some salty water on for 48hrs and you'll soon know!

sorry to hijack a little but what grade steel do you need for a square/round framed chassis?

Normal mild steel will do for pretty much all chassis applications. Carbon steels are stronger but you get problems welding them. Same with some alloy
steels.
If disfunction is a function, then I must be some kind of genius.

Steel is slightly darker as well 
DO NOT PUT ON KNOB OR BOLLOCKS!
