Lastek 41 E (NiFe-CI)

GENERAL DESCRIPTION

Ferronickel cored electrode for welding grey, nodular and alloyed cast iron. Due to the low heat input, the high tensile strength and
ductility, successful welds can be made on heavy or highly stressed sections.
Lastek 41E can be used for joining virtually all types of cast iron and for joining cast iron to different types of steel alloys. The
special formula allows to weld with a high current without the coating turning red. The possibility to use straight polarity without
danger of cracking guarantees full penetration and very strong welds.
Thanks to the pulsating arc, Lastek 41E can be used in all positions (vertical down and up, overhead).
Fully machinable, solid and dense deposit.

APPLICATIONS

Repairing heavy sections of grey and alloyed cast irons, SG iron, meehanite.
Machine bases, motor blocks, gear cases, cast iron dies, pumps.
Repairing casting defects with good colour match.
Hardness: 150-180 HB
