AUS8 vs SAK steel

@UnknownVT - you're welcome :) I never heard of 'INOX'-steel before - I always thought that 'INOX' is just a synonym for 'stainless'. You're right about 1.4110 being closer to 440A than to AUS-8. I think it's somewhere in between and pretty hard to discern in everyday usage. I don't think that they have changed the steel recently but I know that Victorinox does different heat-treatments for the various tools and blades on their knives.

According to information that was on victorinox.com until recently, the steel used for their SAKs contains .52% Carbon, 15% Chrome, 0.5% Moly and .45% Manganese. This is basically the same as 425M.

The Rockwell C harness levels quoted were 56 for the knife blades, 53 for the wood saw, scissors, and nail files, 52 for the screwdriver, can opener and awl, and 49 for the corkscrew and springs. The file is case hardened and chrome plated.

BTW – Inox is the French term for stainless steel.

Very useful Frank, thank you....

does the Victorinox SAK steel not contain Si (Silicon)?

The information you posted - seems to tie up with the web page -
Steel designations and compositions
http://www.canit.se/~griffon/knives/text/steel-designations.html

INOX C 0.52, Cr 15, Mn 0.45, Si 0.6, Mo 0.5.
Victorinox's SAKs, RC 56

that is everything except for the 0.6% Si

(Note: "INOX" is their usage -
and I merely repeated it to make finding the reference easier)

Yes they also listed 0.6% “silicium”. Here is the complete quote -


“For both blades we use chrome molydenum stainless steel with 0.52% carbon, 15% chromium, 0.5% molydenum, 0.45% manganese and 0.6% silicium. After a sophisticated hardening process at 1040°C and an annealing temperature of 160°C the blades achieve a hardness of RC 56.
*
The woodsaw, scissors and nail files have a hardness of RC 53, the screwdriver, tin opener and awl a hardness of RC 52, and the corkscrew and springs RC 49.
*
The metal saw and file, in addition to the special case hardening, are also subjected to a hard chromium plating process so that iron and steel can also be filed und cut.
*
The separators have been made from aluminium alloy since 1951. This makes the knife lighter and easier to carry in one's pocket. Formerly these separating layers were made of nickel-silver.
*
The rivets are made of brass and the outer casing of cellidor, made in the USA.”


This is essentially the same information that used to be on the victorinox.com site. It is now online here -

INOX

Short for:
->"inoxidable" french for unoxidizable,

-->that is to say, 'unrustable', or

--->'stainless'
 
Are you sure that some of the surgical steels aren't some of the Sandvik steels .They were made for things like razors.Another thing is that todays surgical steels found in scalpels are throw away blades .Perhaps different steels than the older ones that were resharpened . Recently I was pleased that some nurses asked how scalpels were made !!
 
Surely, this must be a record!
