Chromium on the corrosion resistance of stainless steel decisive role in the definition of stainless steel, ω (Cr) ≥ 10.5%, which is the main element of stainless steel, corrosion resistance, the higher the chromium, corrosion resistance higher possible. This is because the steel in the oxidation of the medium can be formed to Cr2O3 as a stable substrate surface …STAINLESS STEELS are iron-base alloys that contain a minimum of about 12% Cr, the amount needed to prevent the formation of rust in unpolluted atmospheres (hence the designa- tionstainless). Few stainless steels contain more than 30% Cr or less than 50% iron. They achieve their stainless characteristics through

'Stainless Steels have a minimum of 10.5% Chromium (traditionally 11 or 12%). This gives a very marked degree of general corrosion resistance when compared to steels with a lower percentage of Chromium. The corrosion resistance is due to the formation of a self-repairing passive layer of Chromium Oxide on the surface of the stainless steel.Typical microstructure of a duplex stainless steel with about 0.3% nitrogen. Parent metal (left) and fusion zone (right). Note that the fraction of ferrite (dark contrast) in the heat affected zone tends to be higher despite the high concentration of nitrogen.

High carbon high chrome steels are heat treatable as a consequence of the higher carbon content, and are known as martensitic stainless steels (e.g. 410, 416). They do, however, exhibit lower corrosion resistance due to chromium depletion of the oxide film. They exhibit good strength and oxidation resistance up to 750°C, although their creep ...Meanwhile, due to the high raw material cost, the profits of steel mills were compressed again.
