Talk:Monel

possible error
I'm questioning the electrical conductivity of 34% IACS as given in the article under 'Properties' (I believe it should be 3.3%). IACS is conductivity relative to copper. Copper conductivity is 59.6e6 S/m. Monel resistivity according to the data sheet http://www.specialmetals.com/assets/documents/alloys/monel/monel-alloy-r-405.pdf is 0.511 micro-Ohm*m. If I'm not mistaken that translates into 1.96e6 S/m, which in turn is 3.3% of 59.6e6 S/m. Can someone double check this? This is my first contribution to Wikipedia, so be gentle on me :-).

old question
Is Monel advisable for steam application?

Oh really

Another surprisingly high view page
This alloy gets 7000 views per month. But we have such slim content and referencing is not to good overviews. :-( TCO (Reviews needed) 20:31, 21 January 2012 (UTC)

R405 information to add
Established: R405 is a free machining grade. What is not stated: Typically free machining grades with additions of Sulfur or Selenium do not weld well. These elemental additions to an alloys base composition, for chip breaking purposes during machining, is a hindrance to the practice of welding. In materials that weld well these elements are normally kept to very low levels such as 0.05% max by weight.HPAlloys (talk) 17:15, 16 March 2017 (UTC)

Why not tools?
Perhaps the answer is in all the tech-talk? Why not knives etc? At Rockwell 65, it invites the question...in plain English. I understand that Rockwell 62 is considered very hard for knives (very expensive high wear steels S30V, M4, M390, S90V, S110V etc), and I think Rockwell 57 is typical for standard folding and bushcraft knives, including good ol' 1095 high carbon steel. (Normal cheap stainless is often considered too soft to hold an edge.) --2602:306:CFCE:1EE0:6591:4FC6:3374:5763 (talk) 21:51, 20 October 2017 (UTC)Doug Bashford

Other section lacks notability
Half the entries in the "Other" section of uses are single sentences with no source. Specifically, the sections on kitchen sinks, boilers, eyeglasses, stirrups, fridges, and staples seem entirely pointless to include. I don't want to delete a large swathe of the article but these need to be sourced and expanded on or deleted for lack of notability. 66.161.207.235 (talk) 18:42, 2 August 2023 (UTC)

Monel 400 factoid
I've deleted the strange sentence that has split the third paragraph of the introduction into two pieces since April 14th, 2013. There is no mention of the term "puritan alloy" in scholarly literature and its wider use is confined to marketing materials for this specific formulation of the alloy, Monel 400. These marketing materials were the sentence's only citations. In any case, recent analyses of the Sudbury Basin have shown that the impactor was likely a comet. This means that the nickel mined at Sudbury is not meteoritic, and was instead churned up from the interior of the planet during the impact. Georgelazenby (talk) 01:41, 17 October 2023 (UTC)
