Need some help from the forum locating nitriding facility
I have 6 to 8 crankshafts that I want to nitride. I live in northern Arkansas and have checked in Memphis, Tenn. and Little Rock, Arkansas and have found no service. There is a facility in Little Rock, Arkansas that nitrides but has never any done any auto crankshafts. (says he would do the work , but at my own risk.) I located one service but they cannot treat to the full 0.010"-0.020" that I desire. Any suggestions from the forum as to a facility say in St, Louis, Mo. or maybe Tulsa, Oklahoma that has experience with cranks? Thanks for any help. Jerry

Nitrex does production crank nitride, but will look after racers as well.
We have yet to send them a crank, but plan to use them when we need the next one done.

Re: Need some help from the forum locating nitriding facility
Back from the dead threadsurrection!
I'm looking for a place to nitride and micro-polish the factory forged crankshaft from the '06-'09 4.4 liter supercharged Cadillac Northstar.
I'm in VA and can ship to the Detroit area, but it would be great to find somewhere more local.

Aren't currently, there are two distinct Nitride processes, one being plasma (?), and not often offered by same vendor, and both have their own attributes?
So that should be it seems a decision first made?

I don't know who they use, but Burtonsville Performance Machine in Burtonsville, MD polishes cranks and then sends them out for nitriding. I was going to have my stock cast Buick 3.8 crank done, but the inconsiderate jerks magnafluxed it before starting the polishing and found two tiny cracks . From yellowpages.com: 5210 Minnick Rd, Laurel, MD 20707, (301) 490-3131 - that's just off I95 between DC and Baltimore. Worth a call, at least, if you are in northern VA.

Re: Need some help from the forum locating nitriding facility
It's a ready to install crank and I don't want to incur a bearing turn on it if avoidable. I understood the low temp/gas nitride process could work on a nearly ready to install crank. I need to talk to an expert to find out if the micro-polishing process can clean up any irregularities from the gas nitriding process.
Thanks! I'll give them a call. I live in Springfield, VA, so they're not so far.ijames wrote: ↑Tue Feb 04, 2020 10:18 am I don't know who they use, but Burtonsville Performance Machine in Burtonsville, MD polishes cranks and then sends them out for nitriding.

I don’t know what you consider local (seems everything local to me is a 4-6 hour drive)
Few of the local racers use them. Very quick turn around too.

Re: Need some help from the forum locating nitriding facility
Bodycote has many locations...I used them here in NY for a motorcycle crank...Waiting to be treated were many crankshafts, local racers recomended the place.They used a process called ferritic nitrocarburizing. they wanted to know the type of forged steel, they chage by weight.. I've had other bike cranks done at a different place, they called it by the known name Tufftride....
The treating was done on fully machined cranks...I was told the journal size can increase slightly, about .0003...The shop machined the journals for this expected size increase...Nitriding can warp the crank a bit sometimes. One of the four I had done at different times needed to be straightened..

If you want US based, Moldex and Kellogg are no question the best for nitriding depth. I've had Moldex do 1mm depth.

Check with Lloyd at Springfield Custom Auto Machining.
He does crank polishing and surly knows of the local nitriding sources.
