Product Description

Submerged Arc Welding Flux HJ431

HJ431

Specification: AWS  A5.17 F6A2-EL12

Applications:

Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural implements, machinery, boilers, bridges, structural steels.

Characteristics: HJ431 is a fused glassy granulated flux

Metallurgical behavior:

High silicon and manganese pick-up is obtained.

Grain size: 14 to 60 mesh

Basicity: 0.7(BIIW)

Damp flux should be re-dried at 300-350℃ for 2 hours. Rust, grease and moisture on the weldment should be removed before welding.
