Dura Bar is cancelling production of Ni-Resist bar stock

Dura Bar is cancelling production of Ni-Resist bar stock

Dura Bar is cancelling production of Ni-Resist bar stock

(OP)
Hello all,

Dura-Bar has stated they will no longer be manufacturing Type 1/2 Ni-Resist bar, and sourcing has become a problem as supplies dwindle. It sounds like there are many folks out there having this same issue.

Does anyone have any information regarding utilization of other materials as a substitute? Thank you in advance.

What properties of Ni-Resist are important to your application?

RE: Dura Bar is cancelling production of Ni-Resist bar stock

20 years ago we were casting our own hollow bars as supply was problematic even then.
This is an austenitic gray cast iron. Good corrosion resistance, excellent dimensional stability, and non-magnetic.

Thank you for your responses.

Yes, along with the statement above from EdStainless "Good corrosion resistance, excellent dimensional stability, and non-magnetic" is usage as a bearing ring around solid nickel plated cylinders/trunnions. I believe a percentage of graphite within the material composition assists it's utilization as a bearing between different metals.

We are currently looking into two other options of ASTM 395 60-40-18 and ASTM 395 65-45-15 to assist with procurement of materials while continuing to meet required material specifications.

So far, with the information you have given, Graphalloy would be an ideal replacement if you can tolerate the price.

TugboatEng, thank you for the lead. I will give them a call and check it out. Much appreciated.

Do you have a UNS alloy number for the material you were buying?... or similar-too UNS number??

F4700X (X=1, 4, 5, or 6) and F43030. There are a few grades so I am not sure which they are using.
