\u00b9Les recommandations de couple se r\u00e9f\u00e8rent \u00e0 des surfaces sans bavure et lubrifi\u00e9es avec un lubrifiant de bonne qualit\u00e9. Les recommandations de couple sont calcul\u00e9es en partant d’un coefficient de frottement de 0,14, n\u00e9cessitant un lubrifiant de bonne qualit\u00e9. En cas de lubrification insuffisante, la pr\u00e9charge peut varier consid\u00e9rablement.<\/p>\n

\u00b2La pr\u00e9charge en kN appliqu\u00e9e est calcul\u00e9e avec 65% de Rp0.2<\/sub>. Toutefois, dans la pratique, la valeur peut varier entre 50 et 80%.<\/p>\n

\u00b3Le niveau de r\u00e9sistance typique pour la nuance BUMAX\u00ae<\/sup> Ultra – \u00ab\u00a0La fixation en acier inoxydable la plus r\u00e9sistante au monde\u00a0\u00bb – est de 15.9 (R\u00e9sistance \u00e0 la traction mini. 1500 MPa-Limite d’\u00e9lasticit\u00e9 conventionnelle mini. 1350 MPa). Toutes les fixations en BUMAX\u00ae<\/sup> Ultra sont cr\u00e9\u00e9es sur mesure pour des applications uniques et peuvent offrir diff\u00e9rentes propri\u00e9t\u00e9s m\u00e9caniques avec une r\u00e9sistance pouvant m\u00eame d\u00e9passer la cat\u00e9gorie 15.9. BUMAX\u00ae<\/sup> Ultra est une qualit\u00e9 d’ing\u00e9nierie avanc\u00e9e. Elle b\u00e9n\u00e9ficie d’une assistance technique rapproch\u00e9e pour les projets afin de d\u00e9velopper la solution souhait\u00e9e.
