SG Ni2,5 Tig GMAW-GTAW Solid wires




SG Ni2,5 Tig

 
TYPE 
Solid welding wire for extra low temperature applications.
APPLICATIONS 
Filler metal developed for fine grain steels and cold-tough steels. Typical applications are welding boilers for liquid petrol gas (LPG)
PROPERTIES 

A copper coated, Ni-alloyed (2,4% Ni), solid wire for low temperature steels in applications such as vessels, pipes and in the offshore industry with a minimum yield strength of 470 Mpa. The wire provides excelent impact thoughness down to -60°C.
