Talk:Steel casting

Page contents not supported in other languages.
From Wikipedia, the free encyclopedia

The article states that "[Steel] has a higher melting point [than iron]..." I can't speak to every alloy of steel, but generally steel has a notably lower melting point than iron. — Preceding unsigned comment added by 2603:9001:6802:CE00:91A9:E540:B12B:470A (talk) 00:49, 6 October 2018 (UTC)[reply]

This article is a bit heavy on advertising so I intend to tone it down. Biscuittin 12:05, 4 September 2007 (UTC)[reply]

I'm pretty sure that some ductile and grey cast Irons (especially austempered and compacted cast Irons) are stronger. —Preceding unsigned comment added by 137.207.232.57 (talk) 20:41, 10 April 2008 (UTC)[reply]

Stronger than what? --Wizard191 (talk) 12:34, 12 April 2008 (UTC)[reply]

Article Quality

[edit]

This article has incorrect statements, such as:

  • "Steel casting is a specialized form of casting involving various types of steel". What makes is specialized?
  • "Steel castings are used when cast irons cannot deliver enough strength or shock resistance" (needs a fact this is an opinion, as there are many cart iron alloys which deliver adequate strength and sometimes steel castings are used for other reasons that simply to replace or substitute for cast irons, of which there are many general types.
  • "Steel castings are categorized into two general groups: carbons steel and alloy steel". This is a very narrow categorization, and many steel foundries who produce stainless steels, or manganese steels, would not consider their product to be in either of these categories but in a category by themselves (as an example). The directory of the Steel Founders Society lists several types of steel foundries under ally types.
  • One reference is listed. This is not a good practice for a Wikipedia article.
  • No information on various types of steel castings from the processing point of view, such as molding processes, melting processes, welding, heat treating or NDT.
  • The list created is a boring and dominates the article so much, it looks like the article was created simply to create store this list. This lists should be eliminated. See Wikipedia:Lists, especially the section under tables. The article looked better in some of the revisions from late 2007 to early 2008, minus the links to commerical sites.

Overall the article is poorly written and desperately needs cleanup.

Tags will be added per the above points. Mfields1 (talk) 01:49, 6 June 2009 (UTC)[reply]

more online references should be cited as well; citing Machinery Handbook exclusively, especially a 1996 edition, is not sufficient. Mfields1 (talk) 01:53, 6 June 2009 (UTC)[reply]
  1. Most of your questions can be answered by wp:v, which states: "The threshold for inclusion in Wikipedia is verifiability, not truth". All of the statements are based on the ref supplied (Oberg). As such, if you disagree with any of the statements supply a source that disproves it.
  2. You are correct that more than one ref is always a good thing. As such, I've added the template for it.
  3. Your link to wp:lists is not applicable to this article, as it's an article not a list. A table is the perfect format for the information being relayed. I would be very hard pressed to see you convert it to prose and make it easier to digest.
  4. Nothing on Wikipedia states that verifiability must be reached through online references. As such, this is a moot point.
  5. If you think things are missing from the article please add to it, don't plaster it with unnecessary template and poo poo comments on the talk page. If you don't have time to add the information but have recommendations for improvements, please list them in a constructive way. Wizard191 (talk) 02:36, 6 June 2009 (UTC)[reply]
The list above was meant to be constructive. The article needs significant improvement for the reasons stated above. Mfields1 (talk) 01:10, 7 June 2009 (UTC)[reply]

Article does not cover topic in a broad manner

[edit]

The article does not cover the topic sufficiently. It was a better article before it was expanded to cover only two ASTM grades -

  • A297 – Standard specification for steel castings - heat resistant grades
  • A743 - iron-chromium and iron-chromium-nickel alloy castings – (note: within the scope of ASTM A743 the society does not call these “steel” castings, though the term is used later in the standard).

The table presents an unbalanced image of steel castings as being only from two ASTM types. A user searching this encyclopedia would be presented with a lot of technical information that is better left in handbooks. It may satisfy some editors to create these tables but the article would be more encylopedic to contain more general information about steel castings first, then a separate article could be created for steel casting alloys.

Significant other ASTM standards are not even mentioned in the sense of providing a balance with other ASTM or world wide standards used for steel castings, for example -

ASTM A 27 - Standard Specification for Steel Castings, Carbon, for General Application ASTM A217 - Standard Specification for Steel Castings, Martensitic Stainless and Alloy, for Pressure-Containing Parts, Suitable for High-Temperature Service ASTM A352 - Standard Specification for Steel Castings, Ferritic and Martensitic, for Pressure-Containing Parts, Suitable for Low-Temperature Service ASTM A703 - Standard Specification for Steel Castings, General Requirements, for Pressure-Containing Parts ASTM A732 - Standard Specification for Castings, Investment, Carbon and Low Alloy Steel for General Application… ASTM A781 - Standard Specification for Castings, Steel and Alloy, Common Requirements, for General Industrial Use

There are plenty others this is only a sampling.

I suggest the article title be schanged to "Alloys used in steel casting" Mfields1 (talk) 01:38, 7 June 2009 (UTC)[reply]
