I have been discussing steel with several people lately as I am working on a big project and one that came up was AUS-440C, Now I know AUS steels and 440 Steels but AUS 440C is new to me? ANyone know of this one? Thanks...Rich
 
I don't think there is any such steel designation. Maybe what is being referred to is AUS-10, which is supposed to be the Japanese equivalent to 440C.
 
theres aus 4-6-8-10.............and then theres 440c.....never heard of aus440c although aus 10 is supposed to be very much like 440c
 
Thanks guys, that would make much more sense. With this one fella there was a bit of a language barrier and I think you are right about it being AUS 10.:D
 
maybe this has been a mix up from some German site? Aus is a German preposition meaning "from" or "out of", and could be used like Klinge aus 440C stahl - "blade made out of 440C steel", roughly...
 
I thought "Raus" meant "out of" like Nazi Raus I would see all over Germany in graffiti. Good theory though...;)

Yep. "Raus" means "out of" or, if used on its own, "Get out!". "Aus" can be used in several different contexts, like "er ist aus Finnland" ("he's from Finland") or "die Klinge ist aus 440C" ("the blade is made out of 440C").

Ah I see so Raus would be more like "out of" and Aus would be more like"from" in English. Very good, now we have a lesson in language...LOL Thanks guys...Rich (Vielen vielen Dank)
 
Actually, I'm pretty sure the AUS is short for the metallurgical term austenitic, from the term austenite, a type of micro structure in steels and irons.

Mikey, you are correct...we are just playing around with the term now...LOL

Beat me to it.
 
AUS = austenitic ? doubtful since in use the steel is martensitic. Anyway there is AUS 4,6,8,10 and there is 440A, 440B, and 440C. The difference within each group is carbon content . If a blade is listed as 440 it's usually the cheaper 440A.
 
Actually, you might be right there, I think they are Martensitic rather than Austenitic. As they are heat treatable steels and aren't cold treated. But what in the world does AUS stand for then? Or does the AUS and then the number stand for the amount of austenitic peoperty? like says AUS 8? * being 8 parts or 8%.
