USE OF VANADIUM HIGH-STRENGTH LOW-ALLOY STEELS IN TRAILERS
Abstract:
The trailer case study presented in this report shows that the implementation of High-Strength Low-Alloy Steel with Vanadium (HSLA-V Steel) offers advantages in terms of improved pay load and reduced manufacturing cost
By introducing HSLA-V Steel in the trailer chassis, the amount of steel can be reduced from 3200 kg to 2520 kg. This is corresponding to an overall weight reduction of 21%
The extra effort that may be needed to redesign critical areas is shown to be a good investment. The material cost for the steel sheets has actually potential to be reduced, if the weight reduction is more that the price increase of HSLA-V Steel, compared to Mild steel.
Welding cost has also potential to be reduced. The calculation example presented shows a potential reduction from 1770 Euro to 884 Euro. Assuming an annual transportation distance of 100.000 km, another example shows that 680 kg less weight results in reduction of diesel with 312 litres.
