Chromium is a steel gray, lustrous, hard metal extracted from chromite ores. Because the chromium is the primary alloying element that makes stainless steel corrosion resistant, the chromium-depleted regions are susceptible to preferential corrosion attack. Therefore, high-chromium (for example, more than 20%) austenitic stainless steel is difficult to obtain a martensite structure even after cold working and low temperature treatment. Stainless steel is highly corrosion resistant. Stainless steel can still rust in saltwater over long periods of time and without due maintenance. In addition to having an important influence on the corrosion resistance of negative-number austenitic stainless steel, chromium can also significantly improve the oxidation resistance, sulfidation resistance and resistance to melting salt corrosion of such steels. Fe-Cr alloys containing more than 12% Cr are all ferrite alloys. Stainless Steel Grades In metallurgy, stainless steel, also known as inox steel or inox, is defined as a steel alloy with a minimum of 11% chromium content … To passivate stainless steel, a minimum of 10.5-12% chromium is needed. It is believed that this occurs because the chromium content immediately adjacent to the carbide may be below that required for the stainless steel alloy. Chromiu. Stainless steel must have a minimum of 10.5% chromium count. Anything reducing the localized chromium concentration below the 12% threshold will cause staining or rust. Stainless steel is an iron-chromium alloy that contains anywhere from 10 to 30% chromium which gives the metal high resistance to corrosion.
