Hi, I'm a newbie and doing my research BEFORE jumping right in, costing myself a fortune and making an arse of myself in the process (though I'll do that anyway for sure). T10 steel that many of the Chinese made swords are made of, is it the same as the T10 rebar we can get as cheap as dirt here in the UK? Oh and is it possible to get hold of 8670 steel here in the UK? The British Standards classification is a nightmare.

the T10 used for Katanas is a tool steel with high C (1.0%) and a little tungsten for extra spice

T10 steel

A lot of people say the Chinese T10 is actually closer to 1095. Which is a pretty high carbon steel. Maybe almost a bit much for a sword, definitely harder and more likely to snap or chip then like a 1060 or 5160 sword but it should hold an edge better and be stiffer. If it really is T10 high speed tool steel which is the same as W1 in America it's very strong but it doesn't bend very far before it shatters. We tried to bend a quarter inch plate of hardened W1 at the shop that was out like .003 inch, it flexed a couple inches under the 50 ton press and then exploded sending shrapnel everywhere! I have a picture somewhere I'll try to find it. Come to think of it I should test the hardness of that because it may not have been drawn back it may have been like maximum hardness! Which would mean my story is kind of pointless LOL

I can't say anything about special UK related things but here's some info about 8670: knifeuser.com/8670m-steel-review/Official Chinese T10 can contain a minimal amount of tungsten, probably not really a gamechanger. It should contain a bit more Si than 1095 and be a little bit tougher theoretically. Both have ca.1 % carbon content which makes them better hardenable but also less tough.

A certain someone in the industry has said the Chinese likely use T8 for swords but 10 > 8 for marketing purposes.

T8 is AISI classification, meaning much tungsten, T10 is not (both), it's a Chinese classification, very different, only minimal tungsten, if at all. Probably everyone should think ... The AISI steel equivalent to T10 is 1095. A bit more Si, so less cracking at quenching.

T10 rebar stands for 10mm, nothing to do with steel variant I think.

the GB T8 would make a lot more sense than AISI.

I too have wondered about "T10" in marketing. What we do Know is T10 is a REAL Chinese Steel grade, made by many different Steel Mills. These sites make no mention of Tungsten in Chinese T10, except that "T" is for "Tool Steel".
In the AISI-SAE ( read USA) Steel grade Classification, they use "T" to signify Tungsten steels, my best guess is sellers found a way to label it something it is not, based on the USA terminology which does not translate into this Chinese product with the Chinese system of steel classifications : www.theworldmaterial.com/t10-tool-steel/www.steelnumber.com/en/equivalent_steel_iron_eu.php?zname_id=4717www.chinasteelprofile.com/tool-steel/carbon-tool-steel/t10-carbon-tool-steel.htmlwww.otaisteel.com/t10-steel-stock-china/www.superalloys.net/grades/Special-Alloy/45/49/T10-steel.htmlHere is an old thread that mentions most T10 from China does not have Tungsten: sbg-sword-forum.forums.net/thread/33855/1095-steels-cousins-twins-roommatesThe link from the thread above is definitive proof IMHO that most Chinese T10 does NOT have much (or even traces of) Tungsten, unless it was an "impurity": www.jmst.org/EN/article/downloadArticleFile.do?attachType=PDF&id=15284It seems it's mostly sword re-seller sites in the USA that talk about T10 having a small amount of Tungsten in it. Maybe originally it did have some Tungsten ( ?), but now mostly it does not...and may never have been made that way in China. IMHO T10 ( as it is made now) an over hyped cheap steel, with too much Carbon to be a great blade. AISI-SAE ( read USA) Steel grades do use "T" to signify Tungsten steels, my best guess is makers and sellers found a way to label it something it is not, based on the USA terminology which does not translate into this Chinese product with the Chinese system of steel classifications.

It does have an advertised Tungsten content of 0 to 0,15% - nothing compared to the 10+% of the AISI T-Series. If one was to think the worst of people, one could believe it might be a ploy to hype something totally different to sell for more money and the Tungsten content was only ever on paper. Unless you have an XRF, you'll never know if any T10 ever had Tungsten.

Unless you have an XRF, you'll never know if any T10 ever had Tungsten. I agree without testing no one would know....If you could provide a link that traces back to China would help.
I found a Seller claiming .3% Tungsten ( battlebladesinc[dot]com/what-is-it-t10) and I seriously doubt that unless proven otherwise. I am looking for technical sites that mention the true Chinese standard.
Like you say from "Zero", means it does not need Tungsten at all to be sold as T10. Since it's "optional" steel mills would have financial incentive not to add. That is not to say there is no one who does...
