Description and Applications |
HM308L is a gas
metal arc welding wire to be used with Ar+0.5～2.0% O2
shield gas. The metal deposits show excellent resistance
to inter-crystalline corrosion due to its extremely low
carbon content, and shows an even higher strength in
high temperatures.
Welding of low carbon 18% Cr～12% Ni stainless steels for
chemical engineering plants, textile industries, and
generators. |

|
Guideline in Usage |
|
While high
X-ray quality is required, stable spray transfer
mode should be maintained with a low current and
slow welding speed using a pulsed arc power
source. |
