The longitudinal profile is thermally treated at 350-450[deg] C. The crash box (3, 4) for integrating motor vehicle between the bumper transverse support and a vehicle longitudinal support, comprises a longitudinal profile (5) made of a steel alloy, which consists of carbon (0.15-0.30 wt.%), silicon (0.10-0.70 wt.%), manganese (1.00-2.50 wt.%) chromium (0.10-0.50 wt.%), titanium (0.02-0.05 wt.%), boron (0.001-0.005 wt.%), aluminum (0.01-0.06 wt.%), molybdenum (0.50 wt.%), phosphorus (0.025 wt.%), sulfur (0.015 wt.%) and residual iron including melting-related impurities. The longitudinal profile is thermally treated at 350-450[deg] C. The material of the longitudinal profile comprises a bending angle measured after the heat treatment at 60-80[deg] according to DIN EN ISO 7438. The longitudinal profile consists of two U-shaped configured shell bodies. The wall thickness varies the longitudinal profile, which is configured in truncated pyramid-shape. The longitudinal profile has profiled side walls, and comprises an initial deformation point, and a mounting plate (16) at the longitudinal carrier side end. The longitudinal profile and the mounting plate have wall thicknesses different from each other. An independent claim is included for a method for producing crash box.",
