Solid wire with 9% Cr and 1,0 % Mo, used for welding in all positions creep resisting steel. Used in the chemical industry, in petrochemical plants and in processes synthesis of ammonia. Also used in heat exchangers, boilers, pipes and receptacles a pressure with operating temperatures up to 600 ° C. Its corrosion resistance is higher than 5 Cr 0,5 Mo steels requirements. The deposit and resistant to cold cracking can also be used for the repair of molds of similar composition used in the transformation of plastics. * (X and J Factor checked "on request")
