SMAW Stick electrodes
Cobalt-based thermo shock resistant alloy for overlay applications.
Cladding valve seats, Gasturbine components. Metal working tools like piercing points, forming tools and extrusion dies that are exposed to metal on metal wear in combination with thermal fatigue. Also furnace hardware.
Dur 25U is a Cobalt based electrode developed to resist high impact load, high heat, thermal shock, hot corrosion, compression, abrasion, erosion and many other forms of attack. The weld deposit is machinable with carbide tools.
