    anyone know black oxide mil-std-171 3.3.4? parts are undercooked!

    Thanks, Redpicker. I've pretty much come to the conclusion that our ISO cert on the wall is b.s.. Without a doubt, there are quality policies and procedures that have real impact on the end product, but the "system" is so screwed up...the more you get into it, the more it becomes a self-serving...

    thanks for the moral support. Unfortunately, in this economy, I"m just thankful I have a job of any sort, period. And also, sadly, the parts are so late that the customer (the direct contractor) will probably accept them without batting an eyelid. Perhaps that's how the big bad world of...

    anyone know black oxide mil-std-171 3.3.4? parts are undercooked!

    I'm the QC tech at a machine shop. We just got some parts back from an outside vendor. Cert says they underwent black oxide per mil-std-171, 3.3.4. HOWEVER, our purchase order (from the owner) requested they not give the parts an acid bath before the black oxide, to preserve the tight...
