At the same time, the creep characteristics of the steels were found to be different. A decrease in the carbon content leads to an increase in the long-term creep strength and creep limit at 650°C for short-term tests with time-to-fracture shorter than 10 3 h. The time to fracture of steels with various carbon contents is almost the same in ...

These improve the creep strength by increasing the titanium and niobium content of the weld metal. for best creep resistance an 'H' grade steel should be selected and rutile or acid/rutile electrodes and acid submerged arc fluxes should be used. The steel and filler metal should be selected with as low a ferrite content as possible. However.
