Rolling
Rolling applications, whether hot rolling, semi-hot rolling, or cold rolling, demand materials capable of withstanding extreme mechanical loads, cyclic stresses, elevated temperatures, and severe surface wear. Rolling mill components such as work rolls, backup rolls, mandrels, guides, shafts, and wear parts are exposed to high contact pressures, thermal fatigue, abrasion, and continuous operational loads. Material requirements therefore focus on exceptional strength, toughness, wear resistance, thermal stability, and resistance to crack initiation and propagation. In hot and semi-hot rolling, resistance to thermal shock, oxidation, and heat checking is critical, while cold rolling applications require superior hardness, surface integrity, and dimensional stability to ensure high-quality strip and sheet production.
BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding rolling industry requirements. Advanced hot-work tool steels, cold-work tool steels, high-speed steels, and specially alloyed grades provide an optimized combination of hardness, toughness, and wear resistance. Produced using advanced melting, remelting, and powder metallurgy technologies, BÖHLER materials offer exceptional cleanliness, low inclusion content, and highly homogeneous microstructures. Key quality features include strict chemical composition control, certified traceability, validated heat treatment processes, and comprehensive metallurgical quality assurance. Extensive testing including hardness verification, fatigue evaluation, microstructural analysis, and non-destructive inspection ensures reliable performance. BÖHLER materials help rolling mills achieve extended component lifetime, improved productivity, reduced downtime, and consistently superior product quality.
