STARBLAZE PRIME 11018 M
AWS A5.5: E11018M | EN ISO 18275-A: E 69 4 2 B 32 H5
High Strength | Sub-Zero Toughness | Smooth Arc Characteristics
Engineered for the demands of high tensile, fine-grained steels, StarBlaze Prime 11018M offers radiographic quality welds, high strength (Rp ≥ 680 N/mm²), and superior crack resistance. The smooth, stable arc makes it ideal for precision structural work where impact resistance at low temperatures is critical.
