Application

For welding austenitic stainless steels of types 18-8, 18-12 and 20-10, and is widely applied in petrochemical, pressure vessels, food machinery, medical machinery, fertilizer equipment, textile machinery, nuclear reactions etc, such as the welding of materials like 12Cr18Ni9 and 06Cr19Ni10.

Characteristics

JL-M308 is a 21%-10%Ni austenitic Stainless Steel Welding Wire. The welding arc is stable, the shape is beautiful, and 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.
