whoa there fellas- the gun parts are not mine ! just what a few other people have laying around
Clembert, I was thinking the same thing- have heard the new replicas are better "tensile strength", but would have to see it to believe it.
Unfortunately, this would require what's called "destructive testing"- a pullman test, and grain structure samples of the gun. That means cutting it up into little pieces, machining it into a small table leg shape, then pulling it apart on a special machine, that registers at what force/time it breaks. The grains structure pieces are polished on a special table using various grits of sandpaper disks, then etched with acid, then looked at under a microscope for uniformity/size of the grains. Hardness testing is non-invasive, and a barrel/cylinder/frame could be spot checked, just leaves a small pock mark in the gun- and a reading taken that tells how hard the metal is.
the Italian mfrs. know how "good" their steel is- but they aren't saying- that makes me ask, why ? If they were using top-notch steels like the ROA, chrome moly or stainless, rest assured they'd be bragging about it, because it would be a selling point and advertising feature
