For gases, departure from 3R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to other atoms, as happens in many solids. They have excellent strength, similar to that of low alloy steels, and excellent corrosion resistance especially in seawater and similar environments, where the alloys often outperform many stainless steels.
