Rolled Steel Components
Rolled steel components are made mainly for modern train running gear where the structure and hardness are matched to the customers requirement, taking into account the utilisation requirements. Non-alloyed, moderately-alloyed, as well as highly-alloyed grades of steel are made in order to achievethe the proper toughness, hardness and durability.

High wear-resistance Hatfield type manganese steels are used for making railway gearboxes and and for the jaws of crushing machines – up to 15000 kg piece weight, with max. 300 mm wall thickness (Manufacturing Code MSZ17742).
The rolled steel which was then manufactured and has since been enhanced, are able to meet high limits of endurance which are required for high revolution components. The size-accuracy, shape, finess and excellent surface quality of rolled steel products is ensured by the uniform surface hardness. Rolled steel components were also produced for rubber and plastic industries, roller’s shells for the brick and tile industries as well as components such as rings and pistons for presses – (Internal Manufacturing Code MSZ7380).
High strength, stainless, cold welding steelcastings which are used in the chemical industry and pumps were also manufactured using this technology. These are based on Cr-Ni and contain less than 0.1% C of steel. Steam turbine components were also produced using hot-strength steel grade (Manufacturing Code MSZ1749), and these can be safely operated up to 580° Celcius.
