Bright steel

Blankstahl

Our bright steel is hot-rolled, peeled bar steel with a smooth surface that is as pure as possible, which is manufactured for our customers in special bar quality (SBQ).

Our bright steel is produced on high-performance bright steel lines. Hot-rolled steel bars are peeled, polished and ground by machining to the tightest standard and customer tolerances. A wide range of heat treatment options, mechanical processing and the most precise testing equipment ensure that customer specifications can be met.

High-quality steel

Unalloyed or alloyed quality steels, e.g. fine-grain structural steels suitable for welding, are steels for which there are generally defined requirements such as toughness, grain size and/or formability. However, there are no special requirements with regard to non-metallic inclusions or the degree of purity (in contrast to unalloyed or alloyed stainless steels). Quality steels are generally not intended for quenching and tempering or surface hardening. Unalloyed or alloyed stainless steels should be used for such applications.

Application examples:
Structural steel or steel construction elements

Quenched and tempered (QT) steel

Unalloyed or alloyed quenched and tempered steels, e.g. in accordance with EN ISO 683-1, -2 and if applicable EN 10269, are steels generally used for the production of quenched and tempered and flame- or induction-hardened machine parts, but can also be used in the normalized condition in some cases. Quenched and tempered steels are suitable for components subject to high static and dynamic loads. Unalloyed quenched and tempered steel is used for thinner dimensions and lower requirements. For thicker dimensions and higher requirements, we offer alloyed quenched and tempered steel.

Application examples:
Drive shafts, ball hubs, flanges, rotor shafts, connecting rods, connecting elements, linear systems, turbine and generator shafts

Case-hardened steel

Case-hardened steels, e.g. in accordance with EN ISO 683-3, are steels with a relatively low carbon content for components that are carburized or carbonitrided and then hardened. These steels are used wherever a combination of different properties is required, e.g. for gear components with different stresses on the tooth root and tooth flank.

Examples of applications:
Gear wheels, shafts

Rolling bearing steel

Rolling bearing steels, e.g. according to EN ISO 683-17, are steels for bearing rings and/or for rolling elements in which balls or rollers are used to separate the moving parts of the bearing. Rolling bearing steels meet defined, high requirements in terms of hardness, hardenability, microstructure, degree of purity, and surface quality. This makes them suitable for the high surface pressures and alternating loads to which rolling bearings are exposed during operation.

Application examples:
Ball bearings, needle bearings, roller bearings, cams

Microalloyed AFP steel

Micro-alloyed AFP steels are precipitation-hardening ferritic-pearlitic steels from hot forming temperature, e.g. in accordance with EN 10267. They are used for components in which the required mechanical properties are set by controlled cooling from the hot forming temperature, by a ferritic-pearlitic microstructure (with sometimes small proportions of bainite and/or martensite) and by precipitation hardening. There is no need for heat treatment of components after hot forming, which reduces processing costs and component distortion.

Application examples:
Connecting rods, pistons, injection systems, crankshafts, trailer couplings / ball rods
