AVESTA FCW 316L EAS 4 PW-FD STAINLESS WIRE (FOXcore 316L-T1)
Gas-Shielded Wires, Stainless Steel, All Position
AWS A5.22 E316LT1-4(1)
Characteristics and typical fields of application
Rutile flux-cored wire of T 19 12 3 L P / E316LT1 type with controlled weld metal ferrite content (3 – 6 FN measured with Fischer FeriteScope). Particularly for good cryogenic toughness and lateral expansion down to –196°C as specified for LNG applications. Also fulfills AWS A5.22 / SFA-5.22 E316LT1-4J and E316LT1- 1J. The fast freezing slag offers excellent weldability and slag control in all positions. Easy handling and high deposition rate result in high productivity with excellent welding performance and very low spatter formation. Increased travel speeds as well as good slag removal with little demand for cleaning and pickling provide considerable savings in time and money. The wide arc ensures even penetration and side-wall fusion to prevent lack of fusion. Suitable for service temperatures from –196°C to 350°C. The scaling temperature is approximately 850°C in airBase materials

Operating data
Welding with standard GMAW power source with DC+ polarity. No pulsing needed. Backhand (drag) technique preferred with a work angle of approximately 80°. 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 for welding outdoors is 18 – 25 l/min. The heat input should not exceed 2.0 kJ/mm, the interpass temperature be limited to max. 150°C and the wire stick-out 15 – 20 mm. Post-weld heat treatment generally not needed. In special cases, solution annealing can be performed at 1050°C followed by water quenching.
Typical Applications
The wire is recommended for single and multi-pass welding in all positions
