Description: E309LMoT1-1/4 is an all position flux-cored stainless steel wire designed to run with 75% Ar-25% CO2 or 100% CO2. This wire has a smooth spray like arc transfer at higher amperages and at lower amperages a globular transfer. The slag is easily removed at all amperages.
Application: Requiring high strength and resistance to pitting and stress corrosion for use in marine, chemical and petroleum industries. Can be used to weld 22% Cr duplex’s (UNS S31803) and 25 Cr Duplex’s to type 316/316L and to carbon steel.
