Delivering exceptional fatigue strength
BUMAX fasteners provide superior fatigue resistance compared to standard products. Because fatigue fractures typically originate at stress concentrations caused by inclusions, slag or surface defects, we prioritize premium raw materials. By combining advanced metallurgical processes with an excellent surface finish, high-tensile strength and rigid quality control, we guarantee exceptional fatigue strength.
Fatigue testing
Our fasteners demonstrate outstanding fatigue resistance compared to standard A4-80, thanks to their higher yield strength, reduced inclusion content and enhanced surface quality. For applications with extremely high-fatigue demands, BUMAX duplex grades offer even greater performance.
