Hardened washers cracking

Hardened washers cracking

Hardened washers cracking

(OP)
I'm curious to know how most on here specify washers.  How do you harden them without making too brittle?

RE: Hardened washers cracking

DG72;
Are you sure the observed failures were not caused by hydrogen embrittlement???

RE: Hardened washers cracking

DG72, I don't use them often, but when doing I use F-436 flatwashers. Have not heard of any cracking.

Regards,

Mike

Thanks for the reply.  We have used washers quite a bit, but rarely see cracks.  We specify our washers to be case hardened.  These cracked prior to service.

RE: Hardened washers cracking

Sounds like either hydrogen embrittlement or quench cracking from heat treatment.
