cracked scania wheel rim

[xamtex]

was out in a 15 plate scania tonight and had a slow puncture on the o/s front so called out the tyre guy.he took the wheel off and got his soap spray out and the rim was cracked where the centre fits to the rim. he said its not uncommon on these and hes seen it on 68 and 69 plate scania too.....should we be worried???

Not at all I've had that with a volvo and mercedes.

[TruckerJoe]

Had 2 on my Merc in just over 2 years. Been told its common on the Merc also

Crap recycled steel, and manufacturers trying to save weight by making wheels thinner.

Pick-up a wheel from an 80's F10 then pickup a wheel from Fh4..

Also recycled steel corrodes faster than 1st quality steel,

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 also like big griffin says there's more and more recycled steel being used

The proportion of recycled material in steel doesn`t affect it`s quality.
Steel made to differing specs, with different prices, will be of different quality, but the amount of recycled content isn`t really relevant.

A lot of the problems is heating then cooling overtime it weakens them

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 don`t agree that it`s down to the use of recycled content in the steel. It may be poor quality steel, but that isn`t down to recycling content.

"Steel is 100 per cent recyclable. It can be reused over and over again without any loss of quality. Scrap is therefore a valuable raw material for steel production."

Scrap was always part of the charge loaded into steel furnaces, years ago I spent time in Sheffield steelworks laboratories testing samples from open-hearth and electric furnaces, quality was checked with care,whatever the feed to the furnace consisted of.

Might just be down to the usage of the individual vehicle.

Are the roads of today more rougher and potholed than those of yesteryear, or is that the rose tinted glasses viewpoint?

And has anyone noticed this with trailer wheels?

[largebloke1969]

I had both my front rims cracked within weeks of each other on a daf 105 xf a while back

[El Deano]

Had the exact same thing on a Daf XF 65 plate on Friday.

Just chain the dodgy one up and crack on. She'll steer OK with one wheel.

[corij]

chances are its chinese steel once again. my bro who works in engineering near Paris was telling me the chinks go to great lengths now to hide the origins of their finished steel, such is the bad name it now has.

Whoops!

Would the snowflake/plobbers, and Trucking Legends know how to do that, I don't remember that syllabus whilst doing my CPC

I wonder if its driving over the pot holed mess our roads/motorways are now is causing things to crack and fall apart.

Blimey that could have been really nasty.

I am shocked
