ABSTRACT:
An alloying element in the form of metal powder as a part of the flux composition with regard to nucleation agents and/or nitrogen binding elements and strong deoxidizers alloyed iron powder where the alloying content exists in an essentially more diluted state than hitherto has been used in the commercially available alloying metals wherein a practical application of the micro alloying technique is possible, which is used when producing fine-grained steels, also for a reproducible production of filler metal by using an iron based powder either in the as condition or diluted with a boron free unalloyed iron powder as a raw material in the production of filler metals such as stick electrodes, agglomerated fluxes, flux cored wires, in that it contains boron within the limits 0.005% and 0.5%.
