Hi guys, I don't really know this steel so I'll like your input on it since I'm looking to get a knife that is made of it...Thank's Treg!!!
 
I googled this steel and got confused !! In some of the knife references it's said to be equivalent to 440C. However the composition listed is [even on a chinese steel maker website] .12 C, 1.0 Si, 1.0Mn, .75 Ni, 16-18 Cr. Thats not even close to 440C !!! Did someone have the wrong designation ? Or maybe some advertising BS ,oh I mean hype !!!
 
With all the great knife steels available for a maker to choose from, help me understand the desire to gamble on an unknown.

I really have to admit that I have a prejudice against all these Euro and proprietary designations, used by some knife companies, makes me feel like someone is trying to scam me.

Probably need to educate myself about the Euro ones, however.
 
Don , the steel industry has tried to establish a uniform numbering system for steels rather than have each country have their own numbers .That's good ! The final answer is to look up the chemistry .As a metallurgist I can give a very good idea of the performance just with the chemistry .It's not really rocket science. I agree that with so many known steels it doesn't make sense to enter the unknown !!
 
Ok guys I'm not looking to get a knife made of 10Cr17 so that I have a knife made of it...the knife that I'm interested in wich is a BlackJack Grunt, is now made of 10Cr17. Before it was made of AUS8 wich I know is a decent steel but now it's in 10Cr17 wich I know nothing of, that's why I wanted your help to find out if it was comparable to AUS8 'cause if not I won't be getting the knife. Thank's!!!
 
AUS8 makes an excellent knife .I used the CS Master Hunter in AUS8 for years as my primary hunting knife and it served me well. 10Cr17 ?????
 
According to the data we've all been citing 10Cr17 is equivalent to 430 grade stainless.
Here's the source I have been looking at.

This is not a cutlery grade steel.

Either the tech writers at Blackjack who wrote the product description cited the wrong alloy and the blades are actually made of another or their purchasing agent who wrote the contract with the Chinese production company cited the wrong steel and the knives are crap. I'd like to think that the tech writers are incorrect.
 
I've looked over some of those charts and in the "Cr" steels (for lack of a better term) the first number indicates carbon content and the second number chromium content. Example: 7Cr17= .65-.75 C and roughly 17% Cr. So...10Cr17 should be roughly= .95-1.05 C and 17 % Cr. The chart Knarfeng showed is the only one I've found that shows 10Cr17 in the same row with 1Cr17 (which IS around .10% carbon). :confused: I think it's some sort of mistake on their part.
 
Well I kno that the cr stuff is not just used to describe chinese steels. I believe Latrobe owns the patent on some steels used by Henckles and Wusthof that use that type of designation, which is basically a carbon, chrome, Molybdenum listing.
 
I think the Chinese simply don't have an idea what 440C is, because Spyderco was initially told that the Byrd steel was the equivalent of 440C, sooo...
 
I gonna have to get the knife and test it myself I guess, it's a BlackJack it can't be that bad...I'll post a review when I'll get. Thank's to all for your help!!!
 
If it is close to 440C (X105CrMo17), then there is definitely a "0" missing in order to bring the content of carbon to 1% in total and some MO...
 
It appears that any site that referrences the amount of carbon in 10Cr17 gives and amount between .12% and .15%. You would not think that they would all get it wrong.
