Vallourec MSH sections possess good, uniform properties for structural safety and reliability through uniform hardness distribution and low residual stresses. In addition, they have extra-tight corner radii with large, flat connecting areas – a feature that is the direct outcome of the hot-rolling process.
To achieve the best strength-to-weight ratio as well as uniform properties and easy processing in all applications, Vallourec offers MSH sections in wide range of dimensions and steel grades. Besides the standard grades according to EN 10210, these include our proven Forterior® grade series. These materials offer significant weight saving potentials: structures can be designed slimmer without compromising on strength and load capacity or on weldability.
The principle of increased performance and less weight can be maximized with MSH hollow in FineXcell® grades. These fine-grain structural steels offer yield strengths up to an impressive 1000 MPa plus excellent processing and fabrication characteristics.
