- Applications
- Welding of 18%Cr-12%Ni-3%Mo stainless steel, 13%Cr steel, 17%Cr steel and high toughness steel when postheating is not recommended use for welding between dissimilar metal like carbon steel and stainless steel.
- Characteristics
-
- - W 316 is a lime-titania type electrode provided with a good usability and weldability.
- - As the all-weld metal has an austenite structure including Mo., the corrosion resistance against sulfide acid, phosphoric acid and acetic acid is excellent.
- Notes on Usage
-
- - Keep the arc as short as possible and use currents as low as possible.
- - Dry the electrodes at 250~300℃(482~572℉) for 60~90 minutes before use.
- - Remove dirts such as oil and scale from the groove.
