E-308LT
Description:
E-308LT is a specially designed stainless steel flux-cored welding wire used for cryogenic welding of ultra-low temperatures. The electric arc is soft and stable. The droplet is small and uniform, with little spatter, easy slag removal, good welding process performance and full position welding. Optimized the weld metal microstructure, with low temperature impact at -196 ℃ ultra-low temperature stability, to meet the impact of horizontal expansion of the specimen> 0.38mm of the harsh requirements.
use:
Mainly for 304L, 308L stainless steel structural materials such as CNG (compressed natural gas), LNG (liquefied natural gas), LPG (liquefied petroleum gas) three energy storage and transportation equipment field cryogenic environment welding.
Protective gas:
CO2
