HI-Chrome

WSF can produce for you a 15% and 25% Hi-Chrome alloy iron. Typically used in applications of wear resistance and long term heat resistance are required, such as impellers, turbines, and grinding applications. The iron expresses a very hard surface. These high-chromium alloys attribute their superior hardness to the presence of chromium carbides. The main form of these arbides are the eutectic or primary M 7 C 3  carbides, where "M" represents iron or chromium and can vary depending on the alloy’s composition. The eutectic carbides form as bundles of hollow hexagonal rods and grow perpendicular to the hexagonal basal plane. The hardness of these carbides increase hardness to the range of 1500-1800HV.
