Cracked scania wheel rim

Pretty sure scania and Volvo and all manufacturers use buy in wheel rims and tyres from other companies so any of them could get a bad batch :neutral_face: also like big griffin says there’s more and more recycled steel being used :unamused:

I’m sure from when doing metal work, engineering, we was told, the more steel that is used as it’s heated and melted down, it losses carbon content, and other changes within it’s structural make-up. Making it weaker… There’s different processes for different qualities…

But when steel is recycled it is melted down, the carbon and other ingredients can be adjusted. Generally the steels available today are better quality than previously, both because of a better understanding of materials science, and also from better control of the processes.
If sub-standard materials are being used, it is a failure of the truck maker or supplier in their quality control methods, of someone speccing a cheaper material to save cost, or someone speccing a lighter material to save weight.
I do agree that there is plenty of scope for failure, but I dont agree that its down to the use of recycled content in the steel. It may be poor quality steel, but that isn`t down to recycling content.
