To fit within its expanding high-strength steel product line, the company has changed the branding of its namesake product to ChrōmX 9100 (Grade 100) and 9120 (Grade 120) rebar, both sold under the ASTM A1035 specification. ChrōmX 9000 bar provides high strength with ductility, as well as high corrosion resistance—five times more than standard carbon steel—outperforming epoxy-coated and galvanized rebar for corrosion protection, product engineers contend. They attribute the high performance features to the steel’s chemistry and unique microstructure; absent damage-prone coatings, ChrōmX 9100 and 9120 can be handled and fabricated just like conventional rebar.
The 9000 products allow for high strength designs, reducing construction costs, increasing efficiencies and resolving rebar congestion issues. These efficiencies are well recognized by the construction industry, MMFX officials note. Building codes and guides supporting high strength designs are available through the American Concrete Institute, International Code Council, and American Association of State Highway and Transportation Officials.
