Application

Used for high-temperature resistant products such as high-temperature furnaces and coal coking equipment, such as 2520 steel, and can also be used for composite layer surfacing welding and welding of dissimilar steels.

Characteristics

The Welding Wire is a 26%Cr-21%Ni series pure austenitic Stainless Steel Welding Wire, which has good high-temperature corrosion resistance and can reach 1200（. The welding arc is stable and the weld formation is well-formed. 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.
