ZT · HJ260 (low manganese high silicon medium fluorine)
· Conform to: GB / T17854-1999, F308-H0Cr21Ni10
· Description: HJ260 is a smelting type low-manganese high-silicon medium-fluorine flux. It is gray glass-like particles with a particle size of 2.0-0.28mm (10-60 mesh). Using DC power supply, welding wire is connected to the positive electrode, the arc is stable, and the welding seam is beautifully formed.
· Application: It can be used with austenitic stainless steel welding wire, such as H0Cr21Ni10, H0Cr21Ni10Ti, etc., to weld the corresponding acid-resistant stainless steel structure, and it can also be used for roll overlay welding.
