E309L standard: Complies with GB/T 17853-1999 E309LT1-1, equivalent to AWS A5.22-1995 E309LT1-1. Performance introduction: This product is an ultra-low carbon stainless steel flux cored welding wire, suitable for welding 24% Cr-13% Ni type low-carbon and ultra-low carbon stainless steel. Due to its low carbon content, it can resist intergranular corrosion caused by carbide precipitation. Even without stabilizing elements such as niobium and titanium, it can still resist intergranular corrosion caused by carbide precipitation. Purpose: Used for welding stainless steel of the same type, as well as for welding composite steel and dissimilar steel, and can also be used for nuclear reactor pressurecontainerWelding of inner wall transition layer and internal components. Recommended welding parameters: Φ 1.2 current 180-200A, voltage 27-28V, Φ 1.6 current 160-300A, voltage 28-32V, CO2 gas flow rate 20L/min, wire extension length 15-20mm, welding speed 35cm/min,welding torchTilt angle of 80 °, current type
