Use in Shuttle SRB Hold-Downs[edit]

The article has a citation needed on the Space Shuttle hold-down stud section. This NasaSpaceFlight forum post quotes a NASA "SRB Critical Items List" document as saying "All components are Inconel 718 (except shim)." https://forum.nasaspaceflight.com/index.php?topic=21156.msg570281#msg570281

I can't find the corresponding NASA document online, but I suspect the article's statement is correct. Olawlor (talk) 06:50, 13 April 2020 (UTC)[reply]

Pronuciation?[edit]

How do you guys pronounce it? — Preceding unsigned comment added by 75.117.147.94 (talk) 13:20, 21 February 2012 (UTC)[reply]

It's pronounced; ink-o-nell — Preceding unsigned comment added by 80.4.57.101 (talk) 14:28, 8 March 2012 (UTC)[reply]

Typo?[edit]

From the text:

"...or by threadmilling on machining center..."

should there be an article in there? I.e. threadmilling on a machining center. 24.118.61.250 (talk) 23:58, 5 April 2009 (UTC)[reply]

Fixed. Thanks. Wizard191 (talk) 23:41, 6 April 2009 (UTC)[reply]

Welding[edit]

Inertia welding of 718 is used almost exclusively in rotating components for aircraft engines, that should be mentioned in the welding section. —Preceding unsigned comment added by 96.33.82.176 (talk) 00:01, 7 October 2010 (UTC)[reply]

Additional Uses[edit]

A number of books by former astronauts (eg, Jim Lovell's book on Apollo 13) mention that the oxygen tanks on the Apollo Command Modules were made from Inconel, not only for their strength, but because of their good insulating properties. —Preceding unsigned comment added by 121.218.205.13 (talk) 09:25, 13 January 2011 (UTC)[reply]

Can we improve "solid solution strengthening"?[edit]

I was curious about how superalloys develop strength. Current text says: "high temperature strength is developed by solid solution strengthening" with a link to solid solution. I looked at the article on solid solution, which doesn't explain this strengthening effect in enough detail. I suppose some professor has posted some good on-line notes on this point. Would someone please find it & provide link? --Oaklandguy (talk) 21:10, 17 April 2013 (UTC)[reply]

Solid solution strengthening isn't specific to superalloys. It's a vital article for metallurgy and pretty important for engineering in general. Yes, it also needs work – especially for sourcing and further reading (Further reading links are important for articles like this, because we can't give a full treatment in a simple encyclopedia article alone). You'll probably find solid solution strengthening a bit better than Solid solution though. Andy Dingley (talk) 21:18, 17 April 2013 (UTC)[reply]

Thanks! I see you edited the link to "solid solution strengthening" rather to "solid solution". This definitely improves the current article on Inconel. -- Oaklandguy (talk) 21:37, 17 April 2013 (UTC)[reply]

Uses[edit]

"...the engine combustion chamber is printed of Inconel... " The last bullet under uses probably needs a citation like the others. Further, since Inconel is a registered trademark of Special Metals, does Special Metals need to certify the product of 3D printing process? While the Space X product may match the chemical composition of an Inconel alloy, it may not necessarily match the fatigue, strength, hardness etc. etc. of the wrought product. — Preceding unsigned comment added by 75.166.82.124 (talk) 12:37, 15 August 2014 (UTC)[reply]

Proposed merge with Inconel 625[edit]

insufficient information to justify a separate article Ita140188 (talk) 08:57, 14 October 2015 (UTC)[reply]

What is solutionized?[edit]

Is this heating it under pressure in the presence of hydrogen? -G (talk) 15:16, 5 April 2017 (UTC)[reply]

use in Nuclear industry - only USA and only by miscalculation?[edit]

It is said, that Inconel-600 is quickly degrading in nuclear applications. That is why it was never used in USSR and was immediately prohibited in Germany after the first corrosion incident. In USA Westinghouse Electrics though kept producing and selling Inconel-600 built reactors, offloading its eventual degradation problems to NPP operators. It is said that this material lead to 2002 almost-breach of reactor vessel ( https://upload.wikimedia.org/wikipedia/commons/f/f3/Davis-BesseHole.png ). It is speculated, that ban on Inconel-600 use was reason of AP-1000 project death spiral and eventual bankruptcy of W.E.

Can we say more about the SX300 and SX500 'Inconel' used by SpaceX in their rocket engines[edit]

Can we say more about the SX300 and SX500 'Inconel' used by SpaceX in their rocket engines ? - Rod57 (talk) 01:52, 22 October 2020 (UTC)[reply]

Biased[edit]

Ford uses, BMW uses, Jaguar uses, Tesla claims. Why phrased like that? 37.33.74.55 (talk) 18:48, 3 February 2022 (UTC)[reply]
