Description GMAW wire for 0.5 % Mo alloyed boiler, plate and tube steels as well as in pressure vessel and structural steel engineering. Highly-quality, very tough deposit of high cracking resistance, non- ageing. Approved in long-term condition up to +550 °C service temperature, low temperature toughness to -40 °C. The wire shows good feeding and welding characteristics, resulting in smooth welding and wetting behaviour. Uniform copper bonding with low total copper content.
