COBALTHERME-6
AWS: SFA 5.13 ECoCr-A
EN ISO CODE:
Cobaltherme-6 is a cobalt based electrode depositing a weld metal having 28Cr - 5W - 1C. The weld metal possesses excellent resistance to oxidation, impact, corrosion and heat. The electrode operates well in AC as well as DC. There are several applications in which this electrode can be used. This includes overlay, surfacing applications, which requires heat resistance, oxidation resistance in combination with impact and mild abrasion. Typical applications include, shear blades, dies, valve seats, hot metal handling equipments.
