Le fil de soudure Koronet ER309LSi<\/a> est un fil solide con\u00e7u pour le soudage MIG\/MAG, utilis\u00e9 principalement pour r\u00e9aliser des assemblages entre l\u2019acier inoxydable et l\u2019acier au carbone ainsi que pour cr\u00e9er des couches tampons (transition). Il est utilis\u00e9 en atelier, en assemblage et en production, o\u00f9 la durabilit\u00e9 et la stabilit\u00e9 de la soudure sont importantes.<\/strong> <\/p>\n

L\u2019alliage se caract\u00e9rise par une teneur accrue en chrome et en nickel, ce qui assure une structure aust\u00e9nitique du m\u00e9tal soud\u00e9 et une bonne r\u00e9sistance aux fissures. La faible teneur en carbone (d\u00e9signation L) r\u00e9duit le risque de corrosion intergranulaire, tandis que la teneur accrue en silicium (Si) am\u00e9liore la fluidit\u00e9 de la piscine de soudure, l\u2019humidification des bords et la qualit\u00e9 des faces de soudure. <\/p>\n

Le fil ER309LSi est particuli\u00e8rement recommand\u00e9 pour assembler les aciers inoxydables de type 304\/304L et 316\/316L avec des aciers structurels, ainsi que pour rev\u00eatir les couches de base avant de souder davantage avec des fils destin\u00e9s aux aciers inoxydables, par exemple type 308LSi.<\/p>\n
