thanks BRUV: I had no idea that my customer should have supplied us with confirmation of acceptance. The only confirmation we received was in the form of purchase orders for the duplex stainless we were supplying and that would not help in obtaining orders from other customers. The mills we were...
In response to Jimsan: The specification reads that the purchaser of the material is the one to certify that the material supplied is produced per the specification. I am sure this would make it very difficult for Norsok to come up with an approved supplier list. This takes the responsibility...
Mcquire is right. C276 will certainly do the job for you. As a lower cost alternative you may want to try a Nitronic 50. It has better corrosion resistance than a 316 or 317 stainless and is often used in salt water applications. It also has better galling properties than the 316 you are using...
IFRS is correct as far as temper goes. The big difference betyween these tempers is that t651 is normally found on cold finished bar or plate products. The t6511 is for extruded products only. Normally when these options are included they mean you have a choice between extruded or cold finished...
Thanks guys. I did not realise there was a difference till I tried degaussing. I guess the only option is annealing. I will let my customer know the bad news.
We have finish machined parts manufactured from 1/2"dia monel 400 bar. We have now found out that these parts have much more induced magnetism than we thought. The bars themselves are magnetic (I assume from the cold drawing process). The test reports show that the material has been stress...
The Waukesha Foundry website says only that "Waukesha 88 (UNS N26055) can be used in any environment where 316 SS is used successfully."
You might want to contact them for more info.

YOU MAY WANT TO HAVE THE SCREW MANUFACTURED FROM NITRONIC 60. IT IS PROBABLY THE CHEAPEST OF THE NON-GALLING ALLOYS IN STAINLESS STEEL.

WE STOCK THE MP35N UP TO 1-1/2"DIA. ANYTHING LARGER YOU MAY HAVE TO HAVE MADE. IF WHAT YOU NEED IS IN MY SIZE RANGE GIVE ME A CALL (416-213-0000) MARK.
If you do not want to go to the expense of using a nickel alloy you may be able to get away with using a duplex stainless steel such as 2205 (uns 31803). It will give you similar strength with about half of the cost. It depends on the temperatures you are encountering and whether they are...
