Requiring long-term strength and toughness, axles, axle parts and housings of commercial and heavy-duty vehicles rely immensely on the quality and durability of the tubes and sections used as the base material.
Economic axle production demands tight tolerances for the outside diameter, wall thickness and length so as to ensure optimal machining and welding properties. The base material has to be amenable to fast and precise machining with low tool wear and constant material properties. In combination with optimized production and delivery logistics, they represent a significant cost factor.
Vallourec offers seamless steel tubes and square and rectangular MSH sections for a wide range of axle applications in all types of commercial and heavy-duty vehicles, trailers and mobile equipment. They feature outstanding material properties in terms of tensile strength, toughness, CEV and weldability. Excellent product quality (i.e. tolerances and straightness) and availability in various processed and machined conditions make them ideal as integrated solutions for economic high-quality axle production.
Their overall material properties make Vallourec axle tubes particularly suitable for use in friction- and resistance-welded axles, forged integral axles and axle units with machined axle hubs (high-grade intermediate product). Special high-strength grades are available for more demanding axle applications.
