1.\u00a0<\/span><\/strong>Introduction aux mat\u00e9riaux 35CrMnSiA<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 Le 35CrMnSiA est un acier \u00e0 tr\u00e8s haute r\u00e9sistance faiblement alli\u00e9. Il poss\u00e8de de bonnes propri\u00e9t\u00e9s m\u00e9caniques globales apr\u00e8s traitement thermique, une r\u00e9sistance \u00e9lev\u00e9e, une t\u00e9nacit\u00e9 suffisante, une bonne trempabilit\u00e9, des propri\u00e9t\u00e9s de soudage (pr\u00e9chauffage avant soudage), de traitement et de formage, mais une faible r\u00e9sistance \u00e0 la corrosion et \u00e0 l'oxydation. Il est g\u00e9n\u00e9ralement utilis\u00e9 apr\u00e8s un traitement thermique \u00e0 basse temp\u00e9rature, une trempe isotherme ou un revenu.<\/span><\/p>\n

IV. Champ d'application du 35CrMnSiA<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 Le 35CrMnSiA est utilis\u00e9 pour fabriquer des composants \u00e0 vitesse moyenne, des composants lourds, des composants \u00e0 haute r\u00e9sistance et des composants \u00e0 haute r\u00e9sistance.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 Fabrication de diverses pi\u00e8ces importantes \u00e0 forte charge et \u00e0 grande vitesse, telles que des engrenages, des arbres, des embrayages, des pignons, des arbres de meule, des manchons, des boulons, des \u00e9crous, etc.<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 Fabrication de pi\u00e8ces r\u00e9sistantes \u00e0 l'usure et \u00e0 faible temp\u00e9rature de travail, de composants de soudage \u00e0 charge variable, tels que les pales, les plaques de vannes et les tuyaux non corrosifs des soufflantes \u00e0 haute pression.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
