Product Description
Submerged Arc Welding Flux HJ431 AWS F6A2 EL12
Standard : GB/T5293 NB/T47018-2011 F4A2-H08A F5A2-H08MnA
Equivalent to:AWS -A5.17 F6A2-EL12
HJ431 is a kind of smelting-type ,red brown to light yellow colored ,glassy granulated flux with high manganese and silicon but low fluorine,mesh 8~14,8~40 and 14~40,Either alternating or direct curren can be used and welding wires must be connected with the positive electrode when direct current is used, The welding technology has good performance.
Usage:
When applied ro welding wires such as H08A,H08MnA and H10Mnsi,it can weld low-carbon steel and some low-alloy steel like 16Mn and 15MnV,as well as ships,boilers and high-pressure vessels.And it also can be used for electro-slag and copper welding.
Cautions:
1.The oil soil,moisture,Iron rust and other foreign substances must be removed from the surface before welding.
2.The flux must be baked under 300-400℃ for 2 hours.
