Never had a failure.

Thats what got me wondering, they have been doing it forever. I have a magnum 5", just recently had chromed, a shop that has been chromeing forever, old spanish guy, but he knows nothing of Hydrogen embrittlement. Would you run my axel after seeing that, Just parnoid because I have alot in a car I am about to finish and hate to see it wrecked over a defective axel. What percentage do you think of axels that suffer from HE issues? Whatch mine be other 1 %

Not very encouraging, this stuff isn't new, nor should it be unknown to a quality plater. It's probably not a "guarantee" of failure, but not very reassuring either. How lucky do you feel?

Here's some more to ponder: http://www.finishing.com/1600-1799/1747.shtml

If you do a web search by "chrome plating and hydrogen embrittlement" you'll find much more to ponder.

Yea thats what I am talking about, most likely I am out about 800 in a chrome axel I am going to hang on a wall because I am unsure, Does HE happen in forged parts?

there were clues leading to this failure that went uncorrected---the ill handleing, the toe in issues,---they should of raised an eye brow to something beyond a different toe setting--

the king pin area likely failed because of the method and quantity of material removed to get the chrome out of the king pin boss, the tapered bolt for securing the kingpin was over tightened causing the fracture--when the king pin boss failed the car was out of control--this led to further damage breaking the axle at the perch area---
Axles mounted like that with split wishbones need some rubber ends on the links to allow for a little flex/bind issues--the use of hard ends/heims will put the axle in a very high stress every time it moves in any direction

Agreed, the only axles i've ever seen break was because of an accident or been badly fitted.

I am running split whishbones and tie rod ends for the end on the wishbones, it that hight stress, and the weight of a blown bbc?

Check to see what revision axel you have (I am sure there are noticeable changes) and wether the changes to make it stronger give you a better feeling for safety. The chrome embrittlement issue? Depends on the design of the axel and what design rules were used for over kill if any. Heck don't use it too scarry!!

Chassis Engineering axles are forged

I believe so are the Socal axles.

Maybe I should look in on the NSRA UK site again as for the most part I enjoyed most of the threads. Sorry to see that you aren't a mod there any longer. Interestingly - as many times as I've been in the UK/Scotland and Ireland, I have yet to see but one rod, and not sure about that one.

CE had a real nice exhibit at the York NSRA show last week. I do like their bolt on IFS system, tho would probably weld it up once in place and proven.
