Cold rolled profiles are produced at Montanstahl by forming round wire rod, which can have a max. diameter of 25 mm, by a continuous rolling process without heating up the material. Cold rolling is a very efficient manufacturing process which has been developed mainly for small sections.
Compared to hot rolling, cold rolling offers some considerable advantages.Excellent surface finish, tight tolerances (h9) and the possibility to produce very small production lots are the most obvious. But furthermore cold rolling gives the possibility to change the mechanical properties of the material and produces certain useful combinations of hardness, strength, stiffness and ductility.
This is completed by selective annealing processes. Montanstahl has placed its strategic focus on high alloyed and stainless steel. The profiles can be supplied either as bars in fix lengths up to 6.000 mm or be recoiled. The bundles can be cut to length with a tolerance of +/- 10 mm. Typical production quantities start at 500 kg.
