Introduction to Stainless Steel - Industrial Metallurgists

Duplex stainless steels contain more chromium and less nickel than 300-series and typically include nitrogen as an additional austenite stabilizer and molybdenum for corrosion resistance. 2205 (22% chromium, 5% nickel, and 3% molybdenum) is a common standard duplex stainless steel, and 2507 (25% Cr, 7% Ni plus 4% Mo) is a common super-duplex steel.

Stainless steel - Wikipedia

Stainless steel's resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen. Corrosion resistance can be increased further, by: increasing the chromium content to levels above 11%;

Commercial sintering of chromium powder metallurgy (PM

6/15/2020 · In concentrations above 11 percent with iron, chromium can provide stainless properties through the formation of an adherent chromium-rich oxide surface film. Stainless steel materials are one of the largest applications of chromium in wrought-steel metallurgy. Chromium was first used by PM in the creation of stainless steel powders in the 1930s [2].

Chromium - an overview | ScienceDirect Topics

Chromium occurs in nature mainly in the mineral chromite; Cr also occurs in small quantities in many minerals in which it replaces Fe 3+ and Al 3+ (Faust and Aly, 1981). The metallurgy industry uses the highest quality chromite ore whilst the lower-grade ore is used for refractory bricks in melting furnaces.
