Acier inoxydable AISI 310<\/h1>\n\n\n

Nr. 1.4845 \/ AISI 310 \/ UNS S31000 est un acier aust\u00e9nitique tr\u00e8s commun qui est appliqu\u00e9 dans un environnement \u00e0 haute temp\u00e9rature. En raison de sa teneur \u00e9lev\u00e9e en chrome et en nickel, il offre une meilleure r\u00e9sistance \u00e0 la corrosion que l'AISI 304.<\/p>\n

L'AISI 310 est l'un des mat\u00e9riaux qui pr\u00e9sente les meilleures performances en mati\u00e8re de r\u00e9sistance \u00e0 la chaleur et aux hautes temp\u00e9ratures. Lorsqu'il est utilis\u00e9 en continu, il peut tol\u00e9rer une temp\u00e9rature maximale de 1100 degr\u00e9s. Sous une temp\u00e9rature aussi \u00e9lev\u00e9e, sa structure interne reste tr\u00e8s r\u00e9guli\u00e8re. Cette structure r\u00e9guli\u00e8re a une grande influence sur la r\u00e9sistance \u00e0 la corrosion des mat\u00e9riaux en acier inoxydable.<\/p>\n

En g\u00e9n\u00e9ral, cet acier inoxydable peut \u00eatre divis\u00e9 en AISI310, 310S<\/a> et 310H en fonction de leur teneur en carbone :<\/p>\n

AISI 310 : C<0.250%<\/p>\n

AISI 310S : C<0.080%<\/p>\n

AISI 310H : 0.040%<C<0.100%<\/p>\n

Et avec l'augmentation de la teneur en carbone, la r\u00e9sistance \u00e0 la corrosion de cet acier sera moins bonne, et sa capacit\u00e9 de soudage sera \u00e9galement r\u00e9duite.<\/p>\n

Application de l'acier inoxydable 310 :<\/strong><\/h2>\n

L'alliage AISI310 peut \u00eatre utilis\u00e9 en continu \u00e0 une temp\u00e9rature de 1500 degr\u00e9s, et de fa\u00e7on intermittente \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 1090 degr\u00e9s. Il a une bonne r\u00e9sistance \u00e0 l'oxydation, \u00e0 la c\u00e9mentation et au soufre, et il a \u00e9t\u00e9 prouv\u00e9 qu'il r\u00e9siste \u00e0 l'atmosph\u00e8re marine.<\/p>\n

\u00a0<\/h2>\n

Acier inoxydable forg\u00e9 310 :<\/strong><\/h2>\n

Cet alliage doit \u00eatre forg\u00e9 \u00e0 la temp\u00e9rature de 2150\u00baF (1175\u00baC), et proche de la temp\u00e9rature de 1800\u00baF (980\u00baC). Pour les petites pi\u00e8ces, elles seront toutes trait\u00e9es directement par refroidissement rapide \u00e0 l'air ou par trempe \u00e0 l'eau apr\u00e8s forgeage. Si ces pi\u00e8ces sont trait\u00e9es par recuit apr\u00e8s forgeage, elles obtiendront la meilleure r\u00e9sistance \u00e0 la corrosion.<\/p>\n

Traitement thermique de l'acier inoxydable AISI 310 :<\/strong><\/h2>\n

Recuit :<\/strong><\/h3>\n

Les pi\u00e8ces fabriqu\u00e9es avec cet acier inoxydable doivent \u00eatre recuites \u00e0 une temp\u00e9rature de 1900\/2050\u00baF (1040\/1120\u00baC), et trait\u00e9es par trempe \u00e0 l'eau.<\/p>\n

Traitement :<\/strong><\/h3>\n

La machine fabriqu\u00e9e en AISI310 est comme les autres machines 18\/8, qui peuvent \u00e9galement fournir des coupes dures et fines. Et son alimentation maximale et sa faible vitesse ont offert la meilleure usinabilit\u00e9. En outre, le traitement des barres d'acier par un l\u00e9ger travail \u00e0 froid am\u00e9liorera la finition de leur surface.<\/p>\n

\u00a0<\/h3>\n

Soudage:<\/strong><\/h3>\n

L'AISI310 peut \u00eatre soud\u00e9 par fusion sous protection et par r\u00e9sistance. Toutefois, l'accumulation de carbone doit \u00eatre \u00e9vit\u00e9e lors du traitement par soudage oxyac\u00e9tyl\u00e9nique. Le risque de fissuration pour cet acier inoxydable est faible. S'il est n\u00e9cessaire de remplir de m\u00e9tal, il est sugg\u00e9r\u00e9 d'utiliser la tige en AISI310. Et apr\u00e8s le soudage, corrosion intergranulaire<\/a> sera \u00e9vit\u00e9e si l'on proc\u00e8de \u00e0 un traitement par recuit.<\/p>","protected":false},"featured_media":35858,"template":"","categories":[],"tags":[],"class_list":["post-35857","blog","type-blog","status-publish","has-post-thumbnail","hentry"],"yoast_head":"\nStainless Steel AISI 310 - Stainless Steel Pipe and Fittings | KAYSUNS<\/title>\n<meta name=\"description\" content=\"Stainless Steel 310 is AISI 310 \/ UNS S31000, is a common austenitic steel for us.
