Chromium is a steel gray, lustrous, hard metal extracted from chromite ores. In 2011, U.S. production of chromium was estimated at 160,000 metric tons, coming almost entirely from recycling stainless steel scraps. In addition, the U.S. imported 430,000 metric tons of chromium, primarily from South Africa, Kazakhstan, Russia and China.
reaction occurs between oxygen difluoride and chromium oxide. Chromium (III) compounds are reduced to Chromium (II) compounds by hypophosphites, concentrated perchloric acid, sodium solution, Cr(III) is readily oxidized to CrO4(-2) by hypclorite, hyprobromite, peroxide, and oxygen under pressure at high temperature. Chromium oxide and rubidium

The steel shall conform to the requirements as to chemical composition specified. The material shall conform to the mechanical properties specified.
chromium is often referred to as chromium (III) and is proposed to be an essential nutrient for the body. Hexavalent chromium, or chromium (VI), is generally produced by industrial processes. How is hexavalent chromium used? Chromium compounds, such as hexavalent chromium, are widely used in electroplating, stainless steel
Stainless steel, due to its superior corrosion resistance relative to most other metals, including steel and aluminum, becomes the cathode accelerating the corrosion of the anodic metal. An example is the corrosion of aluminum rivets fastening stainless steel sheets in contact with water.

The letter "L" after a stainless steel type indicates low carbon (as in 304L). The carbon is kept to .03% or under to avoid carbide precipitation. Carbon in steel when heated to temperatures in what is called the critical range (800 degrees F to 1600 degrees F) precipitates out, combines with the chromium and gathers on the grain boundaries.
