Application

Used for welding materials resistant to atmospheric corrosion such as railway locomotives and freight car bodies, such as 022Cr19Ni10 (S304L) stainless steel and TCS for freight cars.

Characteristics

The welding Wire is a 21%Cr-10%Ni ultra-low carbon austenitic Stainless Steel Welding Wire. The welding arc is stable. Due to the addition of Si, the molten iron has good fluidity and the formed shape is more beautiful. It can be welded in all positions.

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.
