Product Description

SJ301 EL12 EM12K welding flux

Standard: GB/5293-1999 F4AO-H08A F5AO-H10Mn2

EQUIV: AWS-A5.17 F6A0-EL12 F7A0-EM12K

SJ 301 EL12 EM12K welding flux is a kind of fluoride-alkaline-type slag-serial sintered

flux, mesh 10-60 meshes (2.0-3.0mm), basicity 1.6-1.8. It has great capacity of

sulphur removal, phosphor removal and anti- rust. The technology has a good

performance, easy to deslag and with fine appearance of weld, even in the narrow

gap of deep slope entrance. The metal welding seam has a good plastic -toughness,

with low diffusion of hydrogen and fine cold and heat crack resistance.

Usage:

The flux is fit for the submerged arc welding of low carbon steel and low alloy steel,

as well as the fast single-way and double-surface welding of thin steel sheet. And it

is usually used for the sumberged arc welding of liquefied gas storage tanks, gas

bottles, and pipeline steel.

Package:

25kg per kraft paper bag; 1000kg per Jumbo bag

Cautions:

1. The welding flux must be baked for 2hours at the temperature of 300-350ºC before

build up welding

2.Some foreign substances such as rust , grease and moisture on the weldment

should be removed before welding.
