Columbus Steel Alloys

XCr

XCr is an innovative, high grade, stainless seamless steel tubing set, made starting from a solid billet, machine-perforated and cold drawn countless times, to obtain the final required thickness. In this way the very high mechanical characteristics are uniform and constant in the whole round section of the tube. Due to the special chemical composition of this new alloy, the grain structure is not altered by welding during the frame construction. The maximum characteristics are granted also in the joint areas.

Niobium

Niobium is a special steel with Manganese, Chrome, Nickel, Molybdenum and Niobium, where Niobium acts as an alloy-strengthening agent. It is a steel designed to provide superior mechanical characteristics and higher resistance to environmental effects than conventional Cro-Mo steels. Niobium is the only serious choice for a top-of-the-line competition frame, where lightweight and reliability are essential. Columbus Niobium is utilized for the production of the Spirit, Spirit HSS, Max, SL and Life main-triangles.

25CrMo4

25CrMo4 seamless steel has a higher percentage of Chromium, gives to the material good resistance properties to overheating. This steel maintains its properties during brazing and welding, even in the malleable raw state it features excellent mechanical characteristics. Columbus 25CrMo4 is utilized for the production of the Zona, 29r and FAT tubesets.

Cromor

A 25CrMo4 steel, seamed and cold drawn, butted to variable thicknesses using shaped mandrills. Cromor steel is produced starting from a calibrated tube which has already received two drawing processes, before being reinforced in all the possible variable thickness offered by the range.
