GEMET 3276

IDENTIFICATION : Name printed GEMET 3276

CLASSIFICATION :AWS/SFA 5.11 ENiCrMo5 DIN 1736 EL-NiMo 15Cr15W (2.4887)

CHARACTERISTICS :

Heavy coated, basic type electrode depositing Ni-15 Cr-16 Mo-4W-5Fe weld metal. Carbon and Silicon are controlled to the very low levels so as to minimize carbide and intermediate phase precipitation.
