Rolls

Rolls in forming operations require BÖHLER steels with high wear resistance, toughness, and fatigue strength. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable performance and extended service life.

Rolls used in forming operations are key production components in applications such as profile rolling, tube forming, strip processing, and metal shaping. During operation, they are subjected to high contact pressures, cyclic loading, friction, and, depending on the process, elevated temperatures. Material requirements are therefore focused on high wear resistance, compressive strength, fatigue resistance, and dimensional stability. In addition, resistance to surface cracking, adhesive wear, and thermal fatigue is essential to maintain product quality and maximize roll service life. Consistent surface integrity is critical, as roll performance directly influences dimensional accuracy and surface finish of the formed product.

BÖHLER high-performance steels are specifically engineered to meet the demanding requirements of forming rolls. Advanced cold-work and hot-work tool steels, high-alloy grades, and powder metallurgical materials provide an optimized balance of hardness, toughness, and wear resistance. Produced using advanced melting, remelting, and powder metallurgy technologies, BÖHLER materials offer exceptional cleanliness, low inclusion content, and homogeneous microstructures, enhancing fatigue performance and operational reliability. Key quality features include strict chemical composition control, certified traceability, validated heat treatment processes, and consistent hardness profiles. Comprehensive testing, including wear evaluation, microstructural analysis, mechanical verification, and non-destructive inspection, ensures reliable performance. BÖHLER materials help manufacturers achieve extended roll life, improved productivity, reduced downtime, and superior forming quality.
