Difference between machined QQ-N-281 Nicu Forged Bar & Hot Finished?
(OP)
What is the real difference between a part(i.e a large hex nut)that has been machined out of QQ-N-281 Nicu Forged Bar & one that is machined out of Hot Finished Bar?
Are the differences that significant? I know that Forging takes out all of the flaws. But with this material it seems as if forged bar is a little overkill.

For your large hex nut, if you are making more than just a few parts you might consider using hot rolled ring forgings. The added cost of making the rolled rings will be more than offset by the savings in material cost and reduced machine time.
Good luck to you.
