Name: 347L stainless steel flux-cored wire

Standard: GB/T17853E347T1-1 AWS A5.22E347T1-1

-347L main component is low C-19Cr-11Ni-Nb(Ti) can be all position welding, because on the basis of 308L add Ti or Nb, can effectively improve the corrosion resistance.

Application: Used in food machinery, medical instruments, pressure vessels, petrochemical and other occasions, such as 1/0Cr18Ni9Ti(SUS321), 1/0Cr19Ni11NB (SUS347).

Name: 308L stainless steel flux-cored wire

Standard: GB/T17853E308LT1-1 AWS A5.22E308LT1-1

Purpose: GFS-308L is mainly composed of low C-18Cr-8Ni, which is the most widely used austenitic stainless steel welding material.Weld metal contains an appropriate amount of ferrite, which can effectively improve corrosion resistance and crack resistance.Good welding workability -- smooth wire feeding, stable arc, beautiful forming, fine ripple, less splash;The properties of the deposited metal are stable and the pass rate of X-Ray is high.

Application: widely used in petrochemical, pressure vessels, food machinery, medical equipment, chemical fertilizer and other related industries, such as SUS304, SUS304L, etc.

Name: -316L stainless steel flux-cored wire

Standard: GB/T17853E316LT1-1 AWS A5.22E316LT1-1

Description: -316L weld pass metal contains an appropriate amount of ferrite in the austenite structure, so it has excellent crack resistance, low carbon content, anti intergranular corrosion, and has superior low temperature impact performance and good corrosion resistance.

Application: widely used in petrochemical, pressure vessels, food machinery, medical equipment, chemical fertilizer and other related industries, such as SUS316, SUS316L, etc.

Name: -309L stainless steel flux-cored wire

Standard: GB/T17853E309LT1-1 AWS A5.22E309LT1-1

Note: GFS-309L has excellent weldability, weldability integrity and crack resistance because the weld pass metal contains an appropriate amount of ferrite in the austenite structure.

Application: It is widely used in welding of low alloy steel, heat resistant steel, corrosion resistant steel and underpass clad steel.

ER309LMo

Compliance with: GB/T 17853 E309MOLT1-1

AWS A5.22 E309LMoT1-1

Description: ER309LMO is an ultra low carbon stainless steel cored wire. The weld metal has low carbon content. Because of the addition of Mo, it has excellent crack resistance and corrosion resistance.At the same time, ER309LMO flux cored wire has good welding process performance, stable arc, small splash, excellent forming, and can be used for all position welding.

Application: It is used for welding the same type of steel and dissimilar steel.

Welding procedure parameters reference (1.2 flux-cored wire for Ø)

Weld metal radiographic requirements: level

Matters needing attention and operating points:

1. The welding place shall be completely removed from oil, rust, moisture and other surface impurities to prevent the occurrence of pores and cracks during welding. When cleaning, the groove surface and its surroundings shall be polished out with metallic luster.

2. In order to obtain good mechanical properties of the welding seam, it is recommended to use pure CO2 as the protective gas for welding. The flow rate of the protective gas should be 20-25L/min, and the dry-extension length should be 15-25mm.

3. The above suggestions on welding methods, conditions and specifications are for reference only. Users shall conduct process evaluation according to their own welding characteristics before using the welding wire for formal product welding.
