Product Description

Chinese Standard: NB/T 47018-2011

Equivalent To: AWS-A5.17 F6A2-EL12


Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural

implements, machinery, boilers, bridges, structural steels.


Metallurgical behavior: High silicon and manganese pick-up is obtained.

Grain Size: 10-60 mesh 

Basicity: 0.7 (B||W)

HJ431 is a kind of fused glassy granulated flux, colored as red-brown to light-yellow,

high in manganese and silicon but low in fluoride. Either alternate or direct current

can be used. The welding performance is excellent.


When applied with welding wires such as H08A, H08MnA, H10Mn2 or H10MnSi, HJ431

can weld low-carbon steel and some low-alloy steel like 16Mn and 15MnV, as well as

ships, boilers and low-pressure vessels.
