Talk:Spring steel

Moved from article
does this involve inetrstitial bonding - that is the question and with what element??? —This unsigned comment was added by 216.132.2.226 (talk • contribs).

Applications
Piano wire, lockpicks and stage swords? All that steel-making technology just for this?

I'm surprised spring steel isn't used for, say, springs? Doh. 24.85.143.66 (talk) 05:58, 18 April 2011 (UTC) It is of course added.

Definitely used in swords. I don't know of a reference per se but a lot of catalogs. Is that worthy as a reference? I'll hunt around for a proper reference too. — Preceding unsigned comment added by 98.192.21.14 (talk) 22:33, 10 February 2014 (UTC) Check out 'AWE me' on Youtube. He uses a lot of spring steel to forge prop weapons. Common grade for swords is EN45 (BS970), equivalent 250A53. Some stage / reconstruction swords now laser cut from 1075 ready hardened sheet. Spring steel was the best material for swords because the raitio of hardness, or how well the sword will keep its edge, and because it has spring like properties it unlike traditional swords won't crack under pressure instead bending before springing backwards back into its original position. Spring steel is still the best known material for making a sword specifically for its ratio of toughness and hardness that is known to man as most other hard metals would crack under the strain of being used as a sword. — Preceding unsigned comment added by 68.14.104.64 (talk) 14:08, 24 April 2020 (UTC)


 * Isn't this stuff used for truck leaf springs and car coil springs and farming equipment s-tines? Shouldn't that be in the article? AWC3117 (talk) 23:01, 24 November 2014 (UTC)

Although the manufacture of stage swords using spring steel is common, I haven't seen any sources about its use in historical weaponry. — Preceding unsigned comment added by 173.95.135.247 (talk) 16:52, 17 November 2017 (UTC)

It's fairly common in reproductions, for example Dynasty Forge uses 1095 for their Katanas. https://www.dynastyforge.com/guide.php71.86.140.226 (talk) 16:09, 17 May 2019 (UTC)

Perhaps stage people still use carbon steel but blades for competitive fencing have been made only from maraging steel for forty years or more. Much safer because it won't snap off and leave a jagged razor sharp point. John G Hasler (talk) —Preceding undated comment added 01:47, 5 May 2020 (UTC)

castable spring steel alloys?
Is it possible to cast spring steel and get a usable spring? What about sintering or MIM to produce complex leaf springs? —Preceding unsigned comment added by 69.41.40.24 (talk) 15:46, 19 April 2011 (UTC)

Composition
The article summary says that the critical ingrediant is silicon, yet in the table of common spring steels listed, I find other metals, and then sulfer, but no mention of silicon. Is this a mistake? If it's not a mistake, then the article is not self consistent. — Preceding unsigned comment added by 166.70.15.180 (talk) 05:52, 6 May 2012 (UTC)

It also says "Nickel is the key component to most spring steel alloys." Yet only one alloy has it listed? 202.74.196.221 (talk) 09:23, 12 December 2012 (UTC)
 * I am also surprised. In addition, I wonder why the reference page by the supplier used as source does not allow to see the preceding nor the following page. That, in combination with the unusual choice of steels, makes me suspect it is a hidden advertisement. -- Zz (talk) 17:52, 5 February 2013 (UTC)


 * its not an ad, its just based on far too little knowledge and is yet another example of a Wikipedia article that has been edited more than 120 times. Referring to two different editions of Machinery's handbook is eccentric at best and makes it look like there are more references than there are. I don't have the precise edition of Machinery's to check whether the reference to music wire as the most common use of spring steel is right, the 1966 edition doesn't say that and I don't have a later one.  Some other points: there are a lot more than five grades of steel used in making springs.  Nickel is not the only possible alloy (hint: vanadium is good too, among others).  It is nice to know that the primary application of spring steel is swords (assuming that the ordering and number of words in the list indicates importance - a normal assumption in most cases), but that may not be true in countries other than the US (it may be that the reference to swords is an act of vandalism that no one noticed?  That kind of attack is extremely prevalent in Wikipedia).  220.237.45.151 (talk) 21:21, 25 November 2013 (UTC)

When was spring steel invented and by who?
I think there could be more information added, such as the history of spring steel.


 * "Spring" steel is ancient, as long as iron or steel making. However the old springs were of very poor quality - as their metal was poor, a spring had to be extremely large in relation to the stored energy. The leaf springs of early gun locks are a good illustration here.
 * An important development was Huntsman's crucible steel in the mid 18th century. This was a deliberate attempt to make a good quality steel for the increasingly important market for clock springs. Particular care was taken to produce a steel that was not only strong in bulk, but also had a structure that preserved this strength even in thin sections – an important feature for springs, compared to some other high-end steel uses of the period.

Hardness Vs Yield strength discrepancy?
In the article, why does the 301 have max hardness 42 yet yield 1 gigapascal? Given those two are normally related, that hardness seems too low for that yield or vice versa, is there some source for this? — Preceding unsigned comment added by Nereth (talk • contribs) 15:02, 26 August 2013 (UTC) I think you are correct. Typically to qualify as spring steel 301 is normally rolled to a minimum hardness of 380 vpn (1215 m/mm sq yield approx)
 * I think that's the point of spring steel. Very different hardness and yield strength.

springbar tents
A link to the Springbar article might make a good addition to this page — either worked into the article content itself (types of products made with spring steel) or in "See also." Xlea Nollmav (talk) 01:21, 23 August 2023 (UTC)
