■ Detailed explanation

Complies with: Classification Rules for Steel Seagoing Ships II YTM III YM

Equivalent: AWS-A5.17 F6A2-EH12 F7A2-EH14

JIS Y6F53-W41

Note: HJ331 is a smelting medium-manganese and high-silicon flux, which is in the shape of grass green glass with a particle size of 12-60 mesh. Adopt AC and DC, the welding wire is connected to the positive electrode during DC welding. Good welding process performance and good crack resistance.

Uses: with H08A, H08MnA and H10Mn2GA (EH14) and other welding wires, can weld (A3, 20G, 16Mn, 16MnR, A32, E36, etc.) low-carbon steel low alloy steel and high-strength steel for welding shipbuilding and pressure vessels.
