Metrode MOB description: Nominal 0.5% Mo alloying results in improved elevated temperature performance over that of CMn steels. Used for the fabrication of vessels and associated pipework demanding creep rupture strength and ductility at temperatures up to about 450ºC. The Mo content also enhances resistance to hydrogen attack in chemical process plant operation. Favourable mechanical properties of both as-welded and stress-relieved weld metal are also useful in welding structural and general engineering steels for ambient or sub-zero temperature service. In this respect these consumables are related to the higher strength manganese-molybdenum alloyed steel consumables.
