  2. Stainless steel - Wikipedia

    en.wikipedia.org/wiki/Stainless_steel

    Stainless steel, also known as inox, corrosion-resistant steel (CRES), or 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 ...

  3. Pitting resistance equivalent number - Wikipedia

    en.wikipedia.org/wiki/Pitting_Resistance...

    Pitting resistance equivalent number (PREN) is a predictive measurement of a stainless steel's resistance to localized pitting corrosion based on its chemical composition. In general: the higher PREN-value, the more resistant is the stainless steel to localized pitting corrosion by chloride .

  4. Crevice corrosion - Wikipedia

    en.wikipedia.org/wiki/Crevice_corrosion

    The corrosion resistance of a stainless steel is dependent on the presence of an ultra-thin protective oxide film (passive film) on its surface, but it is possible under certain conditions for this oxide film to break down, for example in halide solutions or reducing acids. [4]

  5. Rustproofing - Wikipedia

    en.wikipedia.org/wiki/Rustproofing

    Stainless steel, also known as "inox steel" does not stain, corrode, or rust as easily as ordinary steel. Pierre Berthier , a Frenchman, was the first to notice the rust-resistant properties of mixing chromium with alloys in 1821, which led to new metal treating and metallurgy processes, and eventually the creation of usable stainless steel.

  6. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    The power supply is then taken away and the anodes are simply attached to the steel as a galvanic system. More powered phases can be administered if needed. Like galvanic systems, corrosion rate monitoring from polarization tests and half-cell potential mapping can be used to measure corrosion. Polarization is not the goal for the life of the ...

  7. Passivation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Passivation_(chemistry)

    Stainless steels are corrosion-resistant, but they are not completely impervious to rusting. One common mode of corrosion in corrosion-resistant steels is when small spots on the surface begin to rust because grain boundaries or embedded bits of foreign matter (such as grinding swarf ) allow water molecules to oxidize some of the iron in those ...

  8. Corrosion - Wikipedia

    en.wikipedia.org/wiki/Corrosion

    It is appropriate for metals that exhibit passivity (e.g. stainless steel) and suitably small passive current over a wide range of potentials. It is used in aggressive environments, such as solutions of sulfuric acid. Anodic protection is an electrochemical method of corrosion protection by keeping metal in passive state

  9. Black oxide - Wikipedia

    en.wikipedia.org/wiki/Black_oxide

    Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [2]
