TIG-347L/ER347L

TIG-347L													Classification: YB/T5092 H022Cr20Ni10Nb AWS A5.9 ER347L AWS A5.9M ER347L ENISO14343-A: W(19 9 Nb) ENISO14343-B: SS347L
Stainless Steel TIG Solid Wire
Low Carbon Stabilized Austenitic Alloy
Применение:
For joining low carbon stabilized 19Cr-11Ni-Nb (SUS347) grade stainless austenitic steels commonly used in petrochemical facilities, pressure vessels, food and medical equipment, etc
Характеристики:
1. lncreased content of niobium decreases the likelihood of intergranular chromium carbide precipitation and therefore vulnerability to intergranular corrosion; 2.Stable arc.less spattering,good bead appearance.

Замечания по использованию:
1. Shielding gas: 100% Ar; 2.Shielding gas flow rate: 10-15 l/min; 3. Arc length should be kept between 1-3 mm; 4.Interpass temperature: ≤150℃; 5. Prior to welding, base metal surfaces should be cleaned of grease, oil and corrosion contamination; 6. Take proper protection against wind to prevent blowholes when welding outdoors.
