Hello, I apologize for my bad English language. I'm sure that “K” doesn't stay for “Crudo” (= Raw, i.e. not heat treated to remove brittleness), but I don't know what is its real meaning. Perhaps it COULD stay for Chromium, but I'm not sure about this at all! I don't know, too, in which year the Cogne KM0 (0 = Zero) steel was presented; I can tell only that you can find it in the fifth edition of the manual “L'impiego e il trattamento dell'acciaio“ published by Cogne in October 1959. “Supercromato” isn't a variety of KM0 steel: it means that the barrels made with it were internally chromed in a high quality way.
Best regards, Maxm

Raimey, there isn't a "K" in Italian except for foreign imports. K sound being "ch" bofre e and I and c before a,o,u). But I'm wondering if "K.M.0" (not the quotation marks) might be this?
Il Chilometro Zero (anche chilometro utile, km zero o km 0) in economia č un tipo di commercio nel quale i prodotti vengono commercializzati e venduti nella stessa zona di produzione.
i.e: A quality reserved for that particular region sort like "domain enregistre"? Meaning "K.M.0" would be sort of an advertisement like "speciality of the region" or something close to that.
Ciao Maxim, cosa ne pensate?

Maxm(Maxmurelli?), many thanks for the contribution & worry not about your English.
Acciaio al Cromo Molibdeno(CrMo) KM0, so was there a Cromo Molibdeno and then a Cromo Molibdeno(CrMo) KM0.
Thanks Argo44 and I am aware of the l'alfabeto italiano. Sure I'd say it is advertising but for touting some specific steel feature. I had ideas that the steel was imported & possibly not inland. I believe that the Italians imported some English Steel Co. bar stock about this time also.
Cheers,
Raimey rse

https://www.cogne.com/en/storia/Cogne Acciai Speciali from Cogne Aciers Spéciaux(founded 1911), where as always the Swedish had a hand in steel technology. I wonder if an email to Cogne might net an answer? Cheers, Raimey rse

Argo44: absolutely not, KM0 isn’t an advertisement like “specialty of the region”, or other.
Raimey: Cogne steels are made in Italy. Cogne was - and is - a most respected Italian steel manufacturer, and barrels made with Cogne steels are higly esteemed in Italy. The Vincenzo Bernardelli factory, one of the oldest and most respected Italian gunmakers, was one of the main users of Cogne products. KM0 is indeed one of the many Cogne CrMo steels (KM0 has C = 0,31, Cr = 0,95, Mo = 0,20), but I emphasize again that I’m not at all sure that KM0 stands for CrMo, as many others Cogne CrMo steels use different acronyms.

Many thanks again Maxm. Just a wild guess on Maxmurelli. Any possibility you might check w/ Cogne to determine their bar stock for gun-barrels in the late 1940s & 1950s? Thanks for any efforts.
Cheers,
Raimey rse
