Stainless Steel Solid Wire (MIG)
SH.MG308
Implementation standard :
ASME SFA-5.9 ER308
Description :
SH·MG308 is 21Cr-10Ni stainless steel solid MIG welding wire. The welding process is excellent, the weld forming is beautiful, the splash is less, and the weld metal has good plastic toughness and crack resistance.
Use:
Used in petrochemical, pressure vessels, food machinery, medical equipment, fertilizer equipment, textile machinery, nuclear reactors, such as 12Cr18Ni9(SUS302), 06Cr19Ni10(SUS304) and other materials welding.
Note:
1. Pay attention to the purity of the protective gas, the mixture ratio is recommended to be 98%Ar+2%O2.
2. Gas flow :20-25L/min.
3. Dry extension length :15-25mm.
4. The rust layer, moisture, oil, dust and so on on the welding part are really removed.
5. Outdoor welding, when the wind speed is greater than 1.5m/s should take windproof measures, there must be appropriate windproof facilities to prevent porosity.
