L&L Special Furnace Co. received an order for a medium-sized, floor-standing box furnace that will be used for annealing gun barrels for rifles. This is the second furnace supplied to a Midwest manufacturer of custom firearms and rifles. The furnace has an effective work zone of 34 inches wide x 30 inches high x 32 inches deep. It is designed for use with inert blanketing gas for atmosphere control to minimize surface decarb.

This is the first of several blogs that will describe some of the heat-treatment practices conducted on, handguns, rifle barrels, sniper barrels and artillery (155-mm howitzer).
