Avesta 316LT1 PW Flux Core Wire designed for welding EN 1.4436 / ASTM 316L type stainless steels with excellent 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 EN 1.4571 / ASTM 316Ti for service temperatures not exceeding 400°C. For higher temperatures a niobium-stabilized consumable such as Böhler SAS 4 PW-FD is required.
Features
Avesta FCW 316L/SKR-PW has a stronger arc and a faster freezing slag compared to the 2D type
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, weldability is excellent also in the vertical-up and overhead positions
Applications
Ar + 15 - 25 % CO2 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 20 - 25 l/min
Suggested heat input is max. 2.0 kJ/mm, interpass temperature max 150°C and wire stick-out 15 - 20 mm
Scaling temperature is approx. 850°C in air - Post weld heat treatment is generally not needed
In special cases, solution annealing approx. 850°C in air - Post weld heat treatment is generally not needed
In special cases, solution annealing can be performed at 1050°C followed by water quenching
