NIMOTHERME-NM2
AWS: SFA
EN ISO CODE:
Nimotherme-NM2 is a basic coated, low-hydrogen electrode. This electrode is intended to meet strength requirements after extended post weld heat treatment as required in the construction of nuclear power plants and in the fabrication of components (e.g., steam generators and pressurizers) used in nuclear power plants. The weld metal fulfills the requirements of drop weight testing to determine nil ductility temperature as well as measurement of mils of lateral expansion on broken Charpy V-notch specimens.
