SMAW
- AUSTENITIC STAINLESS STEELS
308L
Description
Rutile-basic coated electrode for 304L austenitic stainless steels base materials
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 18Cr/8Ni stainless steels. Mainly applications include food industries, pharmaceutical equipment and general fabrication. Typical service temperatures are -100°C to 400°C.
