Metallurgical Comparison of 5 Inch/54 Naval Tubes Fired with Naco and Pyro Propellant

Abstract

The effects of two different types of propellant on the surface damage introduced in the 5 inch/54 cannon tube are compared. Based on metallurgical and hardness examination, it is shown that the depth of the damage zone is greater with the Pyro as compared to the Naco propellant. This is related to the higher flame temperature of the former. The type of damage observed is described and discussed.
