  2. Stainless steel - Wikipedia

    en.wikipedia.org/wiki/Stainless_steel

    Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...

    904L is an austenitic stainless steel.It is softer than 316L, [1] [2] and its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all concentrations of sulfuric acid.

    en.wikipedia.org/wiki/Martensitic_stainless_steel

    Martensitic stainless steels can be high- or low-carbon steels built around the composition of iron, 12% up to 17% chromium, carbon from 0.10% (Type 410) up to 1.2% (Type 440C): [8] The chromium and carbon contents are balanced to have a martensitic structure.
