the numerical designators (304, 316, etc) are used before they are defined
The idea that different alloys are designated by numbers should be mentioned somewhere (maybe briefly in the lede) before these designators are used. It it quite disconcerting to see a unadorned and unexplained number in the text (even though it is linked). I don't know enough about how these designators can into existence to add this myself. Something along the lines of "different alloys of stainless steel are given numerical designators such as "304" and "316". -Arch dude (talk) 05:00, 13 August 2018 (UTC)
You are asking a very good question Numbers such as 304 refer to AISI/ASTM standards (American), each one associated with a particular chemical composition Nomber such as 1.4301 refer to EN, (European) Standards) I am nor familanir with Japanese and other standards The EN standards have a plus, i.e. a steel designation Example: 1.4418 stainless steel has the following steel designation:X4CrNiMo16-5-1 which means that the average composition by weight is
4: 0,04%C Cr 16%, Ni 5% Mo 1% balance iron. Some elements in small amounts purposedly added may or may not be listed.
Excessive level of detail
Most of the tables in this article contain an excesive level of detail in the body of the text that are not useful for the general user. While well meaning, this detracts from the accessability and readability of the article. Please consider removing these tables, reordering them to the end of the article, &/or colapsing them, so that article is not bogged down in minutia. As I'm not sure which whould be the most aproprate, I mearly marked the sections affected with the approprate templates, and am making this suggestion here on the talk page so that discussion can be had on which options(s) are best. -- 188.8.131.52 (talk)
Well, I understand that this may be too detailed for some readers ....but hopefully useful for others. Perhaps the best way to simplify is to collapse the table (I have to find out how to do this). This will not erase some of the contents. Mtl-371 (talk) 21:53, 15 October 2018 (UTC)
I collapsed the tables (apparently the defaut setting is not always collapsed, I do not know why). Please let me know if this does not meet the wiki criteria Mtl-371 (talk) 09:41, 16 October 2018 (UTC)
- Collapsing tables is probably a sign of too much detail for a general encyclopedia. Wikipedia is not supposed to be a manufacturer's handbook. Anyone who actually needs the composition is going to have real referencess at hand and could not rely on easily-vandalized WP for any such data. I've taken out the excessively detailed tables. --Wtshymanski (talk) 03:52, 27 November 2018 (UTC)
Collapsing the tables wan an option you suggested, therfore I thought this was OK, and if it did not work that was something I did not do right.You have been so far the only person complaining about it I do not accept your removing them completely, as I feel thy are important to anyone wanting to know stainless teels. However I agree to reduce their size to the most common stainless steel grades used, about 10 per table, but you must put them back. Mtl-371 (talk) 10:45, 27 November 2018 (UTC)
Are guidelines outside the scope of a wikipedia page ?
Please let me know your views: I inserted the following text in the wikipedia page on stainless steel https://en.wikipedia.org/wiki/Stainless_steel
"Selecting the right stainless steel for adequate corrosion resistance is a very frequent concern for designers. There are guidelines which can help 1.For Structural applications; Eurocode 1-4 provides a procedure for selecting an appropriate grade of stainless steel for the service environment of structural members. This procedure is applicable to i)Load bearing members ii)Outdoor use iii)Environments without frequent immersion in sea water iv pH between 4 and 10 v)No exposure to chemical process flow stream 2.Other buiding applications: It is based on the following service criteria: i)Pollution ii)coastal exposure iii)decing salts exposure iv)local weather v) design vi) maintenance reference: http://www.imoa.info/download_files/stainless-steel/IMOA_Houska-Selecting_Stainless_Steel_for_Optimum_Perormance.pdf 3.

This edit has been reverted by Wtshymanski as "not a textbook, not a how-to guide" I disagree, becaust I think this is a very useful information for anyone interested in stainless steels I welcome opinions and comments as to whether this text is outside the scope of the page or not. Thank you January 13, 2019 3:30pm GMT Mtl-371 (talk) 15:37, 13 January 2019 (UTC)
- This is way too much detail for an encyclopedia article. We're not supposed to reprint all of a manufacturer's catalog here. --Wtshymanski (talk) 20:32, 1 April 2019 (UTC)
- =Not a manufacturer catalog yes. But
_in the French Culture we have a hypothesis that "CULTURE" (in uppercase) have to be useless. In computing what's useless is just junk. So I think we should be careful not to delete knowledge used by users of those steels : welder, designers, ... that would be vandalism: and that’s obviously just what has been done.
_The difference between an encyclopedia and a handbook is the perspective. The handbook is a step by step “what to do” list. The encyclopedia explains the mechanism under the procedure: and that’s what you did erase.
_Rousseau defined the encyclopedia as the sum of the human race knowledge,
=> so what you are building from wikipedia is a dictionary. April 5 00:37 UTC
Hello I wonder why the elements of stainless steel are not on there. There is sure a lot of things on it, but most of this seems not very usefull — Preceding unsigned comment added by 2A02:1812:50B:FB00:588A:561B:F4E3:53A7 (talk) 11:49, 24 April 2019 (UTC)
Hello, Please explain what you mean by "elements", I don't understand. As to what is useful, among the 2500 viewers of the stainless steel page every day, it makes sense to assume that some will look for more than superficial information. Who can claim to know what they are looking for? Please also consider that now a lot of information (for instance google books, technical articles and so on) can be obtained only on a pay basis only. Wikipedia's great dream and purpose is to provide access to information on all topics to everyone for free. It follows that there should be as much information as possible on wikipedia, and no self-appointed censors on the level of detail. Mtl-371 (talk) 15:38, 24 April 2019 (UTC)
