When looking beyond Vallourec's family of standard high-strength steels for mechanical engineering applications, Forterior® is the first option you might consider. It has a higher yield strength (between 370 and 500 MPa, depending on the steel grade) and good impact test values guaranteed up to -20° C. The Forterior series consists of six grades with specific mechanical properties (see table below) and outstanding weldability.
Forterior® grades support the design of weight-optimized structures without compromising on performance. This means less material and thus lighter structures, or enhanced performance with the same total structure weight. Popular applications for Forterior® are e.g. highly stressed frame structures for agricultural machinery.
1) Applies for wallthicknesses T > 12 mm: C = max. 0.23 %.
1) AR: As rolled; N: normalized or normalizing formed.
2) Values apply for the lowest wall thickness range defined in Vallourec materials datasheets. Please contact us for further information.
