Hi.

I'm looking for the element composition percentages of C70 steel, and preferably
what the hype about this steel is about?

Thankyou.
 
Never heard of it! What Hype? Many manufactures are making up names that sound hot, but mean nothing. Rember Carbon-V? Mike
 
I have seen posts mentioned of this particular steel on British Blades. It may be a steel manufactured in England, but I am just speculating. Someone here may have the scoop.
 
I understand it is a plain carbon steel, apparently made in Europe.
The name could be suggestive about the carbon content?
What's the hype on it?
 
Browsing through some steel supplier sites and a few other catalogues, it indeed seems C70 is a plain carbon steel, 0.7 % being roughly the carbon content. There is a whole family of low to high carbon steels ranging up from C10, which has a minimal amount of carbon. This actually looks to be the Italian UNI standard, and comparable to AISI, e.g. UNI C60 ~ AISI 1060. Similar/same type names are also in the German DIN standards, so it could be that as well, depending on the case. It should signify the same thing. The Italian steel producer Arvedi mentioned on their site (now offline), for a range of C20-C70, to expect 0.2-0.8 % C and 0.4-0.9 % Mn.
 
The C system thing is part of the German Industrial Standards (DIN) system kind of like the ANSI system in the USA. I like to use the Material numbers as I know most of them. All these damn systems plus the steel factories with their own systems are enough to drive a guy nuts.

C70 is - as Mr. Lovett correctly noted - not a very impressive steel for a knife. Anybody hyping that one must have a lot of the stuff on hand and want to move it out. C70 is a low alloyed carbon tool steel. You should be able to make an OK blade from it but I think even 1095 would make a better knife. Böker use C75 for their new Trenchknife version they have brought out mostly for historical reasons and because it makes a pretty tough blade that will not break easily.
