Hot rolled special profiles are produced at Montanstahl by forming wire rod, which can have a max. diameter of 60 mm, by a continuous rolling process at a temperature of about 1100°C. Hot rolling is by far the most popular and well known technology to produce steel profiles.
Depending on the type of raw material, the desired shape, mechanical properties and the surface aspect, the process of hot rolling was found to be a particularly suitable and cost effective manufacturing method. Compared to conventional billet-based rolling mills Montanstahl operates a special rolling mill which starts from wire rod. This different production set up offers considerable cost savings to customers as smaller lots can be produced and tooling cost are lower. Special profiles can be rolled in a large variety of steel grades like carbon steel, low and high alloyed steel as well as stainless steels.
The sections can be supplied either as bars in lengths up to max. 8.500 mm or coiled up again to suite downstream processes like cold drawing.
Minimum quantities start at 5.000 kg for stainless steel profiles and at 15.000 kg for carbon steel.
