Application

Used in food machinery, medical machinery, pressure vessels, petrochemicals etc, and can also be used for welding stainless steel with similar compositions.

Characteristics

ThE Welding Wire is a 20%Cr-10%Ni-1%Nb Stainless Steel Welding Wire. Due to Nb is added on the basis of SUS308, it can effectively improve the corrosion resistance, especially enhance the resistance to intergranular corrosion.

Chemical composition of welding wire: (Mass fraction)%

Mechanical Properties of Deposited Metal

Note

For MIG welding, the shielding gas flow rate should be maintained at 18-25 L/min using Ar+2%O2 mixture. Wind shields must be employed when wind speed exceeds 0.5 m/s.

For TIG welding:

Gas flow rate should be 5-14 L/min at welding currents between 15-200 A Gas flow rate should be 14-24 L/min at welding currents between 200-320 A

Pure argon must be used as shielding gas. Wind shields are required when wind speed exceeds 1.0 m/s.

Pre-welding requirement: Both MIG and TIG welding processes require thorough removal of rust, oil, moisture and other contaminants from workpieces.

Note: The above parameters serve as reference only. Users shall establish suitable welding procedures based on specific production conditions.
