Hey all!
I was wondering if someone can shed some light on this. I thought I read somewhere a while back that that T10 is the Chinese equivalent of 1095 steel. True?

Hi Roger,
I have a "Hanwei" "Great Wave" katana that is made from T10 and I have been trying to find out where T10 rates in the carbon steel ratings for months, so any information forthcoming will certainly be appreciated.
Regards,,,Boony

I've been trying to find more info on T10 for a bit, myself. I can't seem to have any luck, though. I've been up and down Google more than I care to be for anything, and yet I've only found things made of T10, no technical specifications or anything.

Hi Guys,
This is a cut and paste from SFI,, T-10 - 05-13-2007, 05:00 AM
--------------------------------------------------------------------------------
This is the only usable scrap of data I've found regarding T-10. It is a quote from Dan Zawacki:
According to Daido steels - a japanese supply house, their brand for T-10 (also T-9, is called YK4. The japanese standard designation is SK4 and AISI is W1 or W2. Here's the composition they list for it:
C - .9-1.0 Si - .35 max Mn - .5 max Ni - .25 Max
I am used to seeing Vanadium in W-2, but they don't list it, instead they are listing Nickel. Does this actually meet AISI for W1 or W2?
Anyhow, they say to harden from 760*-820* C, water quench, and temper at 150* to 200*C. Being too lazy to pull up a C to F converter right now, and much too lazy to do the math the long way, I'll trust that someone else will see if these fit into typical W2 temperature ranges. If I had to venture a guess, looking at the chemistry, I'd say it's right about on the mark.
Silicon and manganese in those small quantities would be an advantage to the mill when making the steel. Not sure what the tiny bit of nickel would do. It would drop the both the austenitising temperature and the martensite start tempareature just a smidge (about 4 or 5 C), which might contribute to a nicer hamon. Or not.

Hi Boony,
How do you like the Great Wave? Do you find the blade stiff? How does the blade handle?

Hi Roger,
The "great wave" very nice to look at, I love the long Kissaki, good quality Ito and firmly wrapped, It's a great cutter but personally I find it a little heavy for me, however if you hit something with it, it will certainly make a very clean cut. All up it's my second favourite Kat.
All the best,,,,,Boony Probably shouldn't talk about this sword here as it's a little more than $300

So I was talking to someone from a forge in China. He told me they refer to the 1095 steel as T10, so maybe perhaps that is the reason there is not so much data on it. I have also seen reference of T10 as being a type of tool steel but that just goes back in full circle because what exactly is T10 tool steel? 1095? Now that I think about it. I don't think I have ever heard of any American made cutlery manufacturer refer to T10 steel unless it was outsourced from China. All the T10 steel I have seen are stuff made in China. Am I the only one going crazy about this? I hope someone can clarify.

Hi Roger,
Your not going crazy, when I received the "Great Wave" I posted on all the forums trying to find out what T10 steel was and how it rated, the best I could do was the reply I received on SFI which I have posted above. (meant nothing to me) I had also heard that it was tool steel, but I really don't know. If your lucky enough to find out more let me know.
All the best,,,,Boony

this is something i got off a Q&A
Q Hi Samuel, what it T-10 steel? Is that something like spring steel or 1095. And what size is the Tsuba? 5mm x what? thanks Alan. posted by: alanaustralia (46 ) 6:07 am, Sat 17 Nov A Hi there, T-10 Steel is actually used in industrial applications due to its strength - but is also less brittle then 1095 so it can absorb sudden impacts with out chipping, The length of the Tsuba is 7.5cm. Many thanks for your interest 11:07 am, Sat 17 Nov
hope this helps.

Hi Mysticdx,
Nice find. I even visited that site but didn't find that statement hehe. Wish there was real data on it though.
Thanks!

"Less brittle" doesnt say too much.

You know, if someone is selling steel, they really should be able to give you specs for it. What if you were an engineer building some kind of load bearing widget on a bridge? You NEED to know!
If they can't give you the specs, tell they that if they don't, you'll take your business somewhere else.
I don't know if it's because of my technical/scientific background but sheesh...

Ancal: i absolutely agree with you, if they can't give me specifics then I don't trust their product enough to buy from them;
commissioner: I need a bridge built
engineer: ok
commissioner: what can you build it out of
engineer: steel n stuff
commissioner: can you be more specific
engineer: nope, but you should still trust me and buy my product
commissioner: why?
engineer: cause it's shiny and pattern welded!

there has been a lot of debate on this subject. I myself tried to research it as well and at first I came up with looked very much like what is listed on that page but the more I got into it the less I believed that. the belief that T10 is a Tungstun based tool steel comes from the assumption that it is in the same "steel family" as T15 which is a tungstun high speed tool steel. using the AISI standard would make one assume that the basic mix of T10 is the same as T15 with the major exception being the carbon content. however, the fly in this ointment is that the AISI does not define T10 as any sort of steel. therefor there is no regulation that says "if you want to call your steel T10 it has to made out of this: . . ." T10 comes from China. it is a brand name and not a regulated standard. in China T10 is used as a replacement for 1095. it is not 1095 but neither is it (as far as I can tell) actually a high speed tool steel. T10 does have impurities in it but we do not know what it is and also it can change at any time because there is no entity in China regulating what goes into it. the people who make T10 can cange the mix at any time and so long as it is reletively close to 1095 is serves its perpose and is profitable.
I do think it is a good steel for swords, and it needs to be somewhat consistent so that people will know how to properly heat treat it, but the exact composition is still in question so far as I know.

Well Tom, that page is from a link on a website started by Paul Southren. If you're saying the data is wrong you may want to talk to him about that. T10 is the steel he uses on the SBG Custom and Official SBG sword lines so i assumed it would be correct data since he uses it.
