StarBlaze MIG 182
AWS A5.9: ER 182 | EN ISO 14343-A: W 18 8 Mn
StarBlaze MIG 182 is a premium NiCr alloy solid wire designed for MIG welding of highly heat- and corrosion-resistant nickel-chromium alloys. It deposits a Ni-20Cr3Mn2.5Nb weld metal with outstanding strength, ductility, and toughness, especially after post-weld heat treatment or long-term high-temperature exposure. Ideal for critical applications like cryogenic LNG storage, LPG processing, and dissimilar steel welding, this wire offers excellent performance in creep-resistance (up to 800°C), non-scaling properties (up to 1000°C), and cryogenic impact resistance (down to -196°C).
The wire undergoes ultrasonic and high-pressure jet cleaning after specialised chemical baths, followed by a proprietary anti-spatter silicone coating process for a clean, smooth arc and longer shelf life.
