[QUOTE="Trickymissfit, post: 958587, member: 25383"] i'm sure it's a custom alloy called out by Walther. On the otherhand I've read comments from Walther calling it out as a form of 17ph-4. He just rarely admits it. Most folks that know steels don't spec a 4** series for high heat. Just not a good combo, and chamber temps get serious. Usually starts with 330 or 349 and moves up the ladder. Problem with 330 and 349 is that they will not harden. In otherwords they are Austenitic. In that world you often can't have your cake and eat it. There are steels that would work very well in a rifle barrel, and withstand all the heat we could run at it. Yet they are extremely difficult to machine very accurately. Perhaps somebody will get brave and figure out a way to give us a barrel made of Hestalloy, and also figure out how to resolve it inherent harmonics. On the opposite side of the street, the Army did a little bit of experimenting with a hand full of titanium M14 actions that used a solid ceramic barrel. The groups sizes were bolt gun quality at the minimum, and that barrel could take anything you threw at it! Maybe it's time to be looking elsewhere. gary [/QUOTE]
