NIOBIUM is a special steel with manganese, chrome, nickel, molybdenum and niobium. Columbus's special chemical composition, the combined effect of strengthening for precipitation and reducing the alloy grain size are incredibly enhanced compared to standard steels. Niobium proves more effective than Vanadium as an alloy-strengthening agent. After specific processes of progressive drawing and forming, NIOBIUM undergoes a special heat treatment that gives the steel its final characteristics. It is a steel designed to provide superior mechanical characteristics and higher resistance to environmental effects than conventional carbon steels. The only serious choice for a competition or top-of-the-line frame, where lightweight and reliability are essential. Mechanical characteristics: Rm = 1050÷1150 MPa, Rp0.2 ≥ 750 MPa, Ap5 >14%. Material suggested for TIG welding: OK TIGROD 13.12 (AWS 5.28 ER 80S-G). MIG: OK AUTROD 13.12 (AWS 5.28 ER 80S-G).
