GRINOX 17 E317-16 AWS/SFA 5.4: E 317-16
A rutile coated stainless steel electrode intended for welding of low carbon, molybdenum alloyed, acid resisting austenitic stainless steel of similar composition (317/317L). The deposited weld metal is of X-ray quality. The higher molybdenum content provides better resistance to both acid corrosion and pitting corrosion compared to 316L stainless steel grades.
