TIG-stavar

OK Tigrod NiCrMo-3 är en krom-molybdenlegerad, nickelbaserad trådelektrod för gasmetallbågsvetsning av såväl höglegerade varm- och korrosionsbeständiga stål samt stål avsedda för låga temperaturer. Elektroden är lämpad för nickellegeringar av typ Inconel 625, 825, Incoloy 800 och för 5-9% Ni-stål och liknande stål med hög seghet vid låga temperaturer och dessa legeringar mot varandra. Elektroden rekommenderas även för Avesta 254SMO och Wnr 1. 4547 (SS 2378). Svetsgodset har mycket goda mekaniska egenskaper vid höga och låga temperaturer. Bra motstånd mot punktfrätning och spänningskorrosion . Detta tråd används som påsvetsning av ventilntilkomponenter och rörpåsvetsning inom segmentet olja och gas. Svetsgodset ger gott motstånd mot såväl punkt som spänningskorrosion.

TIG wire of type W 19 12 3 L Si / ER316LSi for welding austenitic stainless steel of type 17Cr-12Ni-2.5Mo or similar. Also suitable for welding steels stabilized with titanium or niobium, such as 1.4571 / 316Ti, for use at temperatures up to 400°C. For higher temperatures, a niobium-stabilized additive material is required, for example BÖHLER SAS 4-IG (Si). Provides excellent resistance to general corrosion, pitting and intercrystalline corrosion in chloride-containing environments. Intended for tough operating conditions, for example in dilute hot acids. The microstructure is austenite with 5-10% ferrite. Maximum use temperature 400°C.
