Stainless Steel Sintered Flux Powder 601

At Weldermetals, we supply and distribute not only the stainless steel welding wires and electrodes but also the flux powder. Sintered flux 601 is a spherical alkaline sintered flux powder used in stainless steel and heat resistant steel welding with an alkalinity value of 1.8 and a particle size of 10-60 mesh.
The welding wire is connected to the positive pole during DC power welding, with features of the stable arc is, beautiful welding joint, hardly recarburization and the chromium burning loss, it is suitable for the welding of low carbon and ultra-low carbon stainless steel. It can be used with ER308, ER308L, ER316L welding corresponding stainless steel and high alloy heat resistant steel, etc., or with 309L for dissimilar welding.
