[MW:4032] Impact

Dear all,
 
I am facing the problem of impact test at -60 deg C in welding.
 
The material is SA 537 Cl 1 and welding consumable used is E7018 C1L ( Advani make). as C1L contain Ni its weld should pass impact but the same is not.  where as impact is OK with E-7018 C3L electrodes.
 
can any body suggest ????
