Introduction of high-carbon ferrochrome basics

Chromium is a shiny gray metal, the density of 7.2, a melting point of 1857 ℃, boiling point 2672 ℃, malleable,Electro Polishing Quality Wire  but becomes rigid when the oxygen-containing, hydrogen, carbon and nitrogen and other impurities and brittle. Inert chemical nature of chromium, oxygen and water vapor at room temperature is stable, chromium and oxygen react begins at above 600 ℃, but after the surface oxide film, the reaction will be slow, when heated to 1200 ℃, the oxide film is destroyed, the reaction becomes faster again.Stainless Steel Shaped Wire At high temperature, chromium and nitrogen, carbon, sulfur reacts. Chromium and fluoride can effect at room temperature. Chromium can be dissolved in hydrochloric acid, sulfuric acid and perchloric acid, nitric acid passivation after the case, no reaction with the acid. Chromium with magnesium, titanium, tungsten, zirconium, vanadium, nickel, tantalum, yttrium alloy formation. Chromium and its alloys have strong corrosion resistance.
