Cette caract\u00e9ristique permet aux profil\u00e9s en acier inoxydable de conserver une bonne stabilit\u00e9 dimensionnelle dans un environnement soumis \u00e0 de fortes variations de temp\u00e9rature.<\/p>\n<h4>Conductivit\u00e9 thermique :<\/h4>\n<p>La conductivit\u00e9 thermique est faible et son coefficient de conductivit\u00e9 thermique est d&#039;environ 16 \u00e0 27 W\/(m\u30fbK), ce qui est bien inf\u00e9rieur \u00e0 celui du cuivre, de l&#039;aluminium et d&#039;autres m\u00e9taux, il pr\u00e9sente donc certaines performances d&#039;isolation thermique.<\/p>\n<h4>Conductivit\u00e9 \u00e9lectrique :<\/h4>\n<p>Il poss\u00e8de une certaine conductivit\u00e9 \u00e9lectrique, mais celle-ci est relativement faible.
