308LCF
Description
Controlled ferrite Rutile-basic coated electrode for 304L base materials used in cryogenic applications
Its basic-rutile coating ensures an excellent combination of welding performance in all positions, except for vertical down, and a high resistance to cracking providing smooth arc transfer. Excellent weldability with a spatter free arc and self-releasing slag result in a very smooth bead appearance. These electrodes are used to weld 304L stainless steels (18/8) with good toughness down to -196°C. These product have a controlled ferrite (3÷8). Mainly applications include pipework and vessel for cryogenic service.
