Bright Steel Wire

With its sites in Hamm, Schwerte and Zweibrücken/Ixheim, the Westfälische Drahtindustrie bright steel division is one of the most important bright steel manufacturers in the world.The company has a recognised high level of expertise in the field of bar steel production.

EZM Driveline – This is the brand name under which EZM can supply you with drawn bright steel, ground bright steel, peeled bright steel and ground-and-polished bright steel in virtually all cold-formable alloyed and carbon steel grades. Our bright steel is characterised by great dimensional accuracy and high-quality, bright surfaces. Compared to rolled and forged products, cold-drawn bright steel offers the advantage of a greater range of processing options. Of very special importance in this context is a lead-alloyed carbon steel for diesel injection pumps. The unique properties of this EZM speciality offer the perfect answer to such contradictory demands as maximum pressure resistance, on the one hand, and optimum machining properties, on the other. EZM is also a specialist for the processing of antifriction bearing steel/ball bearing steel, as well as alloyed high-grade structural steel.

Induction hardened shafts, manufactured to the tightest tolerances according to ISO h6, piston rods for the hydraulic sector or headrests in the automotive sector. These are just three of many hundreds of application examples. Further applications can be found in railroad technology, shipbuilding and renewable energy.

An innovative technological process carried out on specialized machines allowed for the extension of the current offer with products exceeding the requirements of the applicable European standards. The innovative production of the bars allows cost reduction of further processing, thanks to the increased geometric accuracy and ready-to-use surface. Modern production and control methods allow achieving significantly higher product characteristics: Surface quality – up to class 4 Cross-sectional dimension of a bar within the assumed tolerance – along its entire length Roundness deviation – max level 0.0261 (IT / 3) Precise length – tolerance up to 5 mm Straightness of bars – up to 0.3 mm / m No surface decarburization
