ACCORD WITH: GB/T 983 E308-16

EQUIVALENT NORM: AWS A5.4 E308-16

DESCRIPTION:

a.GSE.308-16 weld metal (19Cr-9Ni)is austenite structure, it has excellent mechanical properties and shows good resistance to intergranular corrosion.

b.It can be used for all position welding with excellent performances:stable arc,small spatters, good appearance of weld.And also the welding electrode shows good heat-resistance character,not easy to turn red and gas porosity is not produced.

APPLICATIONS:

·It can be used for welding 18Cr-8Ni(A1S1304),A1S1301,SUS308,etc.

ATTENTION :

a.Before welding,the welding electrodes should be baked at the temperature of 300-350℃for one hour.

b. Using stainless steel brush to clean the weld seam,in order to avoid scrap iron entering and affect its quality.
