1 DescriptionGMAW wire for % Mo alloyed boiler, plate and tube steels as well as in pressure vessel andstructural 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 temperaturetoughness to -40 C. The wire shows good feeding and welding characteristics, resulting insmooth welding and wetting behaviour.
