The destruction or degradation implies deterioration of physical properties of the material. This can be a weakening of the material due to a loss of cross-sectional area‚ it can be the shattering of a metal due to hydrogen embrittlement‚ or it can be the cracking of a polymer due to sunlight exposure. So as long the metal is not be stored properly
