UNS K41545 1

[MechEng13]

Anyone familiar with the above UNS Metal...

We have a customer that believes something they are grinding is made from this. I can't find anything on matweb.com. The customer sent us the following compositions.


Cr 3.14,3.92,2.92
Fe 95.96, 95.15, 95.85
Mo .34, .40,.40

Haven't had any luck finding something that matches the above properties or the UNS #.

Any help would be greatly appreciated.

Thanks,
