Two damascene steel combinations for Hunting Firearm Barrels
The modern generation damascene steels are developed and made by Damasteel AB, Sweden by Rapid Solidification Powder Technology. This
powder method to make damascene patterns is patented in most countries (US Patent No 5 815 790). The new generation barrels are patented
(Swedish patent 9900905-2), patent pending in most countries.
The barrel steels 926.x and 968.x are made by hot isostatic pressing of rapidly solidified powders of two compositions compounded in some
hundred layers. The patterns are further developed during the forging and rolling down to the desired dimensions.
The rapid solidification gives less segregation and finely distributed microstructure. This means improved ductility and fatigue strength compared to
conventional grades.
The modern damascene barrels have gone through a torsion twisting operation . This turns the grain structure towards the transverse direction. The
results are still improved ductility and fatigue properties.
Är patent på stålet så man får inte veta direkt allt vad det innehåller då det är lite hemligt o det förstår man då det är deras nisch
