Characteristics and typical fields of application Rutile flux-cored wire of T 19 12 3 L P / E316LT1 type designed for welding 1.4404, 1.4432 / 316L type stainless steels with good resistance to general, pitting and intergranular corrosion in chloride containing environments. Intended for severe service conditions, e.g. in dilute hot acids. Also suitable for welding steels that are stabilized with titanium or niobium, such as 1.4571 / 316Ti for service temperatures not exceeding 400ºC. For higher temperatures a niobium-stabilized consumable such as FOXcore 318-T1 is required. The scaling temperature is approximately 850ºC in air. Designed for all-round welding and can be used in all positions without changing the parameter settings. Very good slag detachability and almost no spatter formation. Due to the fast freezing rutile slag, the weldability is excellent also in the vertical-up and overhead positions. The wide arc ensures even penetration and side-wall fusion to prevent lack of fusion. Suitable for service temperatures from –120ºC to 400ºC. For flat and horizontal welding positions, FOXcore 316L-T0 DG may be preferred.

Welding with standard GMAW power source with DC+ polarity. No pulsing needed. Backhand (drag) technique preferred with a work angle of approximately 80º. Ar + 15 – 25% CO2 as shielding gas offers the best weldability. 100% CO2 can be also used, but the voltage should be increased by 2 V. Suitable gas flow rate is 15 – 18 l/min. The heat input should not exceed 2.0 kJ/mm, the interpass temperature be limited to max. 150ºC and the wire stick-out 15 – 20 mm. Post-weld heat treatment generally not needed. In special cases, solution annealing can be performed at 1050ºC followed by water quenching.
