Hot rolled special profiles are produced by forming wire rod, which can have a diameter of max. 60 mm, or round bars with diameters up to 110 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 from the shape complexity, the quantity, the mechanical properties and surface condition, hot rolling is considered a particularly cost effective manufacturing process for steel profiles.
Why choose Montanstahl hot rolled profiles
Compared to conventional billet-based rolling mills, within the group we operate special rolling mills, which start predominantly from wire rods. This different production set up offers considerable cost savings to customers as smaller lots can be produced and tooling costs are lower.
We can roll special profiles in a large variety of steel grades like carbon steel, low and high-alloyed steel as well as stainless steel.
We supply these special sections either in bars, in lengths up to max. 10.000 mm, or coiled up again to suite downstream processes like cold drawing.
Hot rolling process: from round to finished profile in multiple passes
Minimum quantities start at 3.000 kg for stainless steel profiles and at 5.000 kg for carbon steel.
