State of the art steel tubes<\/h3>

Advanced High Strength Steels (AHSS) are the latest generation of steels that offer an effective solution to optimising weights and strength in most demanded parts and those with high requirements in shock energy absorption, especially in the automotive sector.\n\nTheir cost is offset by the possibility of mass reduction, which makes them a technologically highly competitive solution.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

Hardened tubes<\/h3>

Induction hardening is based on heating the material by passing it through a high density magnetic field. The heating penetration is a direct function of the working frequency.\n\nPrecise control over this frequency ensures perfect hardening homogeneity throughout the section. The use of Mn-B alloyed steel grades guarantees a high level of impact energy absorption, a property of vital importance in some parts, such as the anti-intrusion reinforcements of vehicle doors.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t

Deformation and wall reduction are lower, maintaining the quality of the surface finish. The Extraductile Tube for headrests reduces wear and tear on the tooling and offers more room for maneuver by deforming it.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
