Excellence in Specialty Steel
FROM PERFECTED TECHNOLOGY TO HIGH QUALITY STEEL THROUGH:
EAF/VIM melting, AOD/VOD secondary refining and ESR/VAR remelting enables the production of materials with a high metallurgical degree of purity
Superior reliability in steel processing ensured by fully controlled production from melting to dispatch
Very low phosphor, sulfur and oxygen content
World class in-house heat treatment facilities
100% UT-tested on state-of-the-art automatic testing equipment
Modern in-house laboratories
Application-driven R&D to benefit our customers
Certified to international standards ISO 9001, ISO 14001, ISO 50001 and IATF 16949 (BGH Lugau)
Approved by e.g. ABS, TÜV, LRS, DNV-GL, BV and major leading companies
Sawed and drilled discs are available from our stocking locations
Chemistry, heat treatment and delivery condition can be tailored to customer specific requirements
In addition to bars, we produce open-die forgings and rolled flat bars
