UNI 6604 Key Material Specifications
I have a metric key for a shaft that is called out to be UNI 6604. Can, or does, anyone out there have any material specifications on this material? I need to know the yield strength specifically. Our vendor is also digging into this but the metric/European standards don't "travel" well.
From searching the web all I have found is "UNI 6604 / ISO 773 / DIN 6885" so if anyone can tell me what any of these standards call out for a minimum material yield strength is that would help me tremendously.
Thanks in advance.
