Tenifer is described as being known to make steel extremely hard (as hard as industrial diamond on the Rockwell Scale) and corrosion resistant. The process essentially makes the barrel impervious to the elements and because it is a hardening process it makes the barrels more resistant to marring or scuffs. Buyer will pay for shipping and insurance. Thank you for looking..
