Apparent Density 13 Fe Spherical Powder, Surface Finish Powder

Material overview characteristics silver, White, Malleable metal. Mechanical properties are altered by impurities, Especially carbon. Iron oxidizes readily in moist, Is highly a strong, Reactive chemically reducing agent air and reacts with steam when hot to yield hydrogen and iron oxides. Dissolves in nonoxidizing acids sulfuric and hydrochloric and in cold dilute nitric acid. Hazards tolerance as oxide fume 10 mg/m3of air. Dust and fine particles suspended in air are flammable and an explosion risk. Tolerance for soluble salts as fe, 1 mg/m3of air.
