Chrome vs Stainless Steel
Many people still confused about the differences Chrome vs Stainless Steel in Application Properties. Chromium is a shiny, brittle and hard metal, and a gray silver color. When heated, chromium forms a green chromate oxide. The metal is unstable in oxygen and soon produces a thin oxide layer. Chromium is mined as chromite ore (FeCr2O4). Chromium ore mining, among others, is in South Africa, Zimbabwe, Finland, India, and the Philippines. The main use of chromium is as a metal alloy as in stainless steel, chrome plating, and metal ceramics.
Chrome plating was once used to provide a silvery layer like a mirror on steel. Chromium is used in metallurgy as an anti-corrosion and glossy impression. In addition, the metal is also used in dyes and paints, to produce synthetic rubies, and as a catalyst in immersion and leather tanning. Chromium (IV) oxide (CrO2) is used for the manufacture of magnetic tape. A person may be exposed to chromium through respiration, food or drink, and skin contact with chromium or chromium compounds. Chromium levels in air and water are generally low.
However, groundwater may be contaminated with harmful chromium (IV) (hexavalent chromium). Chromium (III) is known to exist naturally in a variety of vegetables, fruits, meat, yeast, and whole grains.
Stainless Steel is an iron compound containing at least 10.5% Chromium to prevent corrosion process (metal rusting). This composition forms a protective layer (anti-corrosion protective layer) which is the result of spontaneous oxidation of oxygen to chromium. The ability of rust resistance is obtained from the formation of a Chromium oxide film layer, wherein the oxide layer blocks the iron oxidation process (Femur). Of course, this protective layer mechanism should be differentiated compared to steel that is protected by coating (i.e. Zinc and Cadmium) or paint. It will be different compound between Chrome vs Stainless Steel.
Although the entire category of SS is based on chromium content (Cr), other alloying elements are added to improve SS properties according to its application. The SS category is not like any other steel based on carbon percentage but based on its metallurgical structure. According to the chemical nature of stainless steel the five main classes of SS are Austenitic, Ferrite, Martensitic, Duplex and Precipitation Hardening SS. That all the Chrome vs Stainless Steel.
