DIN 1736                    EL - NiCr 15 FeMn

Material Number                            2.4648

AWS/ASME SFA-5.11         ~ E NiCrFe-3

 

Application / Properties: Basic-covered electrode with 65% Ni and 19% Cr for the welding of:

-Heat and corrosion resistant nickel alloys, e.g. NiCr 15Fe(2.4816),LC-NiCr15Fe(2.4817),NiCr20Ti(2.4951), NiCr23Fe(2.4851), creep resistant up to 800C

-Various nickel alloys and joining them to other steels

-Cryogenic nickel steels, e.g. 12Ni19(1.5680), X8Ni9(1.5662), good cryogenic properties down to 196C.

-Ferritic steels to austenitic steels for operating temperatures above 300C e.g. creep resistant CrMo-steels to austenitic steel.
