Product Description
Chinese Standard: NB/T 47018-2011


Equivalent To: 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: 

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.


Usage:

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.
