A572 gr 50 is 50 ksi yield 65 ksi UTS material. What you were shipped has 
a 36 ksi min specified yield strength, although the UTS may be higher. 
The chemistry is enough different to warrant looking over your weld 
procedures to see if they're suitable. I gather your supplier tried 
pulling a fast one.
