Normal steel vs. Magnetic stainless

Didn't think of the rust. Thanks

Stainless steel in metallurgical definition is steel that contains 14% or more chromium. Other alloying elements such as nickel ca also improve steel’s resistance properties. The amount of free chromium, i.e. not tied up in carbides determines steel’s stain resistance ability. Higher carbon content leaves less free chromium in the alloy, which explains why some of the high and stainless steels with more percent of chromium are less stain resistant than lower grade stainless steels with less chromium and carbon. However, given time and conditions all steels will rust.
