SCC of 17-4PH H900 Drive Rod
SCC of 17-4PH H900 Drive Rod
(OP)
I am currently working on a 17-4PH H900 drive rod that failed by SCC. I am having troubles nailing down the possiable causes of SCC in 17-4PH. We have found traces of cholrine and sulfur in the corrosion products. The rod would have operated at temperatures up to 300-F. Are cholrin or sulfur known to cause SCC at these temperatures? Also, pits were observed along the surface that the SCC intiated.
Thanks for any help anyone can offer.

If you have pits then you have active corrosion. Once that happens CSCC will be a high prob.
One problem with PH grades in there highest strength condition is that the CSCC easily.

Corrosion, every where, all the time.
Manage it or it will manage you.
