GB/T 17853 E317LT1-1 EQUIVALENT NORM:AWS A5.22 E317LT1-1


LY-E317LT1-1 deposited metal contains proper ferrite,so it has excellent weldability, good integrity of weld bead and high crack resistance.


Suitable for welding low C-18Cr-12Ni-3.5Mo stainless steel and the anti-corrosion pressure vessels that request impact toughness at low temperature. Impurities at the weld zone must be cleared away,such as oil,moisture etc. Weld bead shows fine appearance and it has very good welding performance with small spatters and stable arc.

a.Using  CO? as shielding gas,and its purity must be above 99.98%.
b.Windshield must be set up in the welding zone,due to gas porosity may be caused by strong wind.
