Aubert & Duval is the supplier. I can't share the exact alloy, but it's a ChroMoVan steel.
The typical German military barrel steel alloy is 32 CrMoV 12 10 and indeed I have seen batches from French steel mills.
Guess I can post this now, then.
Thanks guys, very helpful.
Do either of you know the H&K RC heat treatment?
I seem to recall that the standard US 4150 was RC 32-34, whereas the H&K was RC 42-46?
I'm a pocket knife nerd originally, prior to getting into guns. Thats an area where steel and RC harnesses are both tremendously important to overall edge retention.
So I imagine that using a harder RC treatment would also factor into overall 'rifling retention.'
For example, a typical bayonet is 51-53RC vs 59-61 for a modern, high end pocket knife. That doesnt seem like much of a spread, but theres a huge difference in overall edge retention. Even the difference between 57 and 60rc is noticeable on a pocket knife.
I'm still not in the clear of why they decided to go with Haenel's AR aside from the rumors(?) that it's supposed to be a cheaper alt. of the 416.
I thought the bundeswehr have already fond of their 416. And The 433 might be more pricey but it got a lot of new features and improvements from the G36. Did H&K messed up in the run somewhere? or did the Haenel and Caracal just have a more powerful political power?
52mio Eur cheaper is a huge chunk on a 250mio Eur deal, the problem is if that saving is mostly down to creative accounting in regards to firearm life span being longer due to that replaceable cam thingy.
Just for the record [don't take this as my statement of supporting the selection]:
A more or less official statement sadi that the Haenel weapon fulfilled all requirements and was "over the expected lifespan" cheaper than the competition.
The 52 million EUR figure cited in this thread does not show up in any official statement I am aware of. I have no idea how close it is to the truth.
I guess this channel will be interesting for you:
