ChromX | An MMFX Innovation

Martensitic Microcomposite Formable Steel (MMFX) is the innovation behind all ChromX products. It is this proprietary steel microstructure, along with a patented chemical composition, that creates the corrosion resistant and high strength properties within the bar, rather than a coating.CMC and its subsidiaries manufacture, recycle and fabricate steel and metal products, related materials and services through a network including six electric arc furnace ("EAF") mini mills, two EAF micro mills, two rerolling mills, steel fabrication and processing plants, construction-related product warehouses and metal recycling facilities in the United States and in strategic international markets.
