HJ331
Standards compliant:
rules for classification of sea-going steel ships II YTM III YM
AWS-A5.17 F6A2-EH12 F7A2-EH14 JIS Y6F53-W41
illustrate:
HJ331 it is a smelting medium manganese and high silicon flux, in the shape of grass green glass particles, with a particle size of 12-60 mesh. it adopts both ac and dc welding, and the welding wire is connected to the positive electrode during dc welding. the welding process performance is good and the crack resistance is good.
use:
Cooperate H08A,H08MnA and H10Mn2GA(EH14)waiting for welding wire, can be welded (A3,20G,16Mn,16MnR,A32,E36 wait )low carbon steel, low alloy steel and high strength steel are used in shipbuilding and pressure vessel welding.

Precautions:
1.flux must be treated for 300 seconds before use ºC-350ºCbake for about 2 hours.
2.before welding, the rust, oil, moisture and other impurities on the welding parts should be removed.
To better ensure the safety of your goods, professional, environmentally friendly, convenient and efficient packaging services will be provided.
