StarBlaze Prime 8018 C2
AWS A5.5: E8018-C2 | ISO 2560-A: E 46 6 3Ni B 32 H5
Crack-Resistant Joints | Cold Climate Certified | Nickel-Rich All-Position SMAW
STARBLAZE PRIME 8018 C2 is a high-performance low-hydrogen electrode designed for welding 3.5% Ni steels in extreme cold environments. Engineered for structural and pressure-grade applications down to –100 °C, it produces clean, tough welds with minimal spatter, smooth bead contour, and excellent post-weld mechanical strength—both as-welded and post-heat-treated.
