I read while ago that Carbon V from Cold Steel is actually 0170-6 (50100-B). Is it still correct?

Thanks, Vassili.
 
It has been tested in the past, way back, a number of knifemakers spark tested it. Recently there are all kinds of rumors floating about concerning what it is and connections between various manufacturers, but spreading such rumors gains little without a concrete statement from one of the manufacturers involved. If you want to find out if Becker and Cold Steel currently run the same steel, then ask in the Becker forum, or ask Cold Steel directly.

I find that if the maker won't tell you what it is or give you a chemistry it is an existing steel on the market packaged to seem like something special.

Carbon V, Infi, etc. If you are really curious 75 dollars will get you a full chemistry on a blade from most metallurgical labs. It will put a spark mark on the blade, but you will have an accurate chemistry.
 
I will not run $75 test to know what is $50 knife made from. I know that it was 1095 then they start using 0170-6 - but what it is now? I thought may be somebody may know.

I heart rumor that INFI is made for Busse by Strator and composition is:
C=0.5 Va=0.36 Cr=8.25 Co=0.95 Ni=0.74 Mo=1.3 N=0.11
This means that this is really propritory steel.

Thanks, Vassili.
 
INFI has already been the study of several elemental breakdowns which have been reported on Bladeforums. There is no need for any rumor.

I'm pretty sure Carbon V was never 1095, since 1095 does not contain Vanadium.
 
1095 contains vanadium. It is typically not reported because to the specification for 1095 does not require vanadium to be reported since it is a residual element.

According to that, it's a 1095, with 0.54 Chrome, 0.40 Manganese, 0.015 Tungsten and 0.15 Vanadium.

Heh, or in other words, pretty much 50100B!

Those Cold Steel fellows, see what great fun they start

Please reference your source for your statement.
 
sorry, but what is the spark test?
normally, if we're interested in finding out the composition of metal, we dissolve a small sample in acid and we perform an AAS on it
the spark test sounds rather, how do we call it, subjective
 
This used to make me curious, but I wonder if in the end, it really doesn't matter... :confused: I have heard all the rumours and read the various posts. From what I can gather, it is whatever is readily available to the manufacturer at the time. They seem to routinely use a good quality high-carbon tool steel with a carbon content in the 0.9-1.0% range and with a few other alloying agents. Those specifications would match 50100B maybe, even O1, but in general terms, unless the manufacturer is going to extreme lengths to give the steel the full treatment, as per Ed Fowler, I think the general performance characteristics are fairly similar. I accept that a manufacturer will use standard marketing strategies to make their product feel / sound special - nothing wrong with that. My 2 cents. Jason.
 
For Chuck,

1095 is governed by ASTM and AISI specificiations. The UNS number for this material is G10950.

Only Carbon, Manganese, Phosphorus, and Sulfur are required for reporting by ASTM and AISI. Everything else is left up to the producer for reporting. I see this causing a lot of confusion for many materials. Just because it isn't listed doesn't mean it isn't in the steel.
 
Ah, Grasshopper. And, just because it isn't listed, doesn't mean it IS in the steel either! ;)

Their Laredo Bowie is over $250. Would that make it worth your while? How much is your curiosity worth to you?

Personally, I'd like to know where you can go or send to have this done. Anybody know?
 
Along with the $75.00 you also have to send them a sample of the steel to be tested. That adds the cost of the knife to the cost of the test.

Though AISI may not require the inclusion of residual elements in its analysis of what elements make up a particular steel, it seems to me that when these elements comprise a percentage high enough to make a difference, they are included.
 
Spark test : One has a source able to produce electric arc between a tester and tested material. Arc removes some material of the surface that mixes in the arc (produces timy amount of plasma that emits light). From the emission light the elements are recognized spectroscopically.

Basically it is possible to analyze spectrum from any plasma. Electric arc is the easiest = cheapest way to produce plasma when the target is conducting material like metal. One can use also lasers etc to produce the emission light.

A sample of sparc / arc measuremet equipments are found from the link below. the 'spark' testester is arc-met

I don't see what difference it makes. Does it hold an edge or not? Does it do what you want it to or not? If so forget about what it is and use it. Thats all you can do really.

I have noticed Carbon V rusts pretty fast if you have one without the baked on finish to protect it. To me heat treatment and hardness are more important because that has a direct bearing on how hard or how easy it is to dull and how hard or how easy it is to sharpen when the time comes.
