Agglomerated flux LH-HF101G
(for: Submerged Arc Welding Flux.)
Execute standards: GB/T 12740-2003 F48A4-H10Mn2A;
(Equal to the standards: AWS F7A4-EH14; F7A2-EM12K )
Description: Agglomerated Flux LH-HF101G is kind of special sintering flux with HighBasicity 2.0,
it is the grey spherical grain, Size of 10mesh to 60 mesh.
The weld slag is easy to be removed on the welded position.
The weldment has the high impact tenacity at low temperature.
Application:
it is suitable for making the important steel structure, high strong steel structure, Chemical pressure vessel and nuclear vessel and various steel pipelinesuch as API pipeline type ofX60;X70 pipeline. It also can be used in multilayer welding, single-welding line with two sides, narrow gap SAW welding voluntarily. theLH-HF101Gflux shall need to combine with SAW wire(eg.: H10Mn2AH08MnMoA;;H08Mn2MoA, EH14,EA1,EA2).
