our customer specifies ultra low carbon content with elevated nickel. Is there any other welding that i can use in this case?

What is your MDMT (minimum Design Metal temperature) at which Impact test to be conducted.

Try E 7018-C3L as it provides Impact test upto to -50degC and also contains Nickel.

E 7018-B2L is a chromium Molybdenum electrode which do not contain much Nickel

Thanks & Regards

hi james,

They really don't have any impact test requirement which is weird though. They require carbon content less than .04% and elevated nickel content.
I don't see any variation with both these parameters.

You should look on SFA-5.5

From the Material ASTM A36 and 275JR I understand they are not LTCS material.

try E 7018C2L or E 7018C1L with the maximum carbon of 0.05% and welding consumable MTC will show lower amounts.

It also depends on the number of Joints you intend to weld,

Thanks & Regards

7018-1 itself will work for-43°C
