Applications and Materials to be Welded
AS P-309L -17 is used for welding of Cr and Cr-Ni alloyed steels that are highly resistant to operating conditions up to 1000°C. It is particularly used for joining stainless steels with low and medium alloyed steels and for root pass applications before welding of surface plated steels. It can be used for cladding of mild steels and to form a buffer layer for hardfacing before welding with AS P-308L -17.
AS P-309L -17 is an ideal electrode especially designed for welding pipes, plates and tanks that are used in chemical, petrochemical, food and paper industries; forged and cast pieces and industrial furnaces that are exposed to high temperatures.
