904L welding consumable

admin

I need to weld a 904L (P45 ASTM group) base material.In the past we have used the Metrode 20.25.4.Cu, ER385 'F6' (ASTM standard) type consumable.However, our current PQR's only cover us for welding P45 type materials with an F45 type consumable where as the above consumable for welding 904L is an F6.Could anyone advise me on any suitable 'F45' type consumables for the GTAW of 904L materials?Our PQR is qualified using Metrode 82-50, ERNiFeCr-1 (F45), would this be suitable? Thanks in advance.Adam
