SMAW
- AUSTENITIC STAINLESS STEELS
308L
Description
Rutile coated electrode for 308 austenitic stainless steels base materials
Its rutile coating ensures excellent weldability in all positions, except for vertical down, and a high resistance to cracking providing smooth arc transfer. High current carrying capacity, minimum spatter formation and virtually self-cleaning slag produce a concave bead with minimal ripple as well as a smooth and clean weld profile. 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.
