This page has a good explanation of the "powered steel process";

http://www.aera.org/Techside/poweredmetal.htm  

Ruger Firearms uses this process for it's guns with great success.
Damascus steel, is multiple layers of steel heated and hammer welded
together into a single piece. That's what gives it that distinct wave
pattern. For gun barrels, Black Powder pressures only are considered as
safe operating levels. But in a sword or edged weapon, (where the
damascus  process got its start) it has excellent properties. Such
"cutlery" is highly sought after by collectors.
