DIN 1736                    EL - NiCr 15 FeNb

Material Number                            2.4805

AWS/ASME SFA-5.11        ~ E NiCrFe-2

 

Application / Properties: Basic-covered electrode with 69% Ni and 16% Cr and 8%Fe  for the welding of:

-Heat and corrosion resistant nickel alloys, e.g. NiCr 15Fe(2.4816),LC-NiCr15Fe(2.4817), or for joining these alloys to unalloyed, low alloy and high-alloy steels; good cryogenic properties down to -196C; heat resistant up to +800C.

-austenitic steels to ferritic steels for operation temperatures above 300C.

-owing to high toughness properties and resistance to cracking, it is well suited for joining difficult-to-weld steels and for repair welding.
