For Nickel & Nickel Alloys

LoTherme-511N

Low heat input electrode for welding Ni-Cr-Fe alloys and dissimilar steels experiencing high temperature. 

Characteristics

LoTherme-511 N is operates in all conventional positions. The weld deposit is hot cracking resistant and does not tend to embrittlement. The weld metal working significantly after more than 10,000 hours at temperature up to 850°C. Has exceptional impact properties, with excellent lateral expansion.

Applications

LoTherme-511 N is used for joining or cladding heat resistant Ni Cr Fe alloys, Inconel Alloys heat, resistant austenitic steels, heat resistant austenitic ferrite materials, Ni-Cr-Fe materials, joining of dissimilar steels, nickel based alloys.

Typical Mechanical Properties Of All Weld Metal

ULTIMATE TENSILE STRENGTH : 61 Kgf/mm2

ELONGATION (L=4d) : 36 %

CVN IMPACT STRENGTH (@RT) : 90 Joules
