Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YS/T 258-1996 "metallurgical niobium powder".
Compared with YS/T 258-1996, the main changes are as follows.
--- increased FNb-0 grades;
--- FNb-1 grades increase the chemical composition requirements of Ta Nb, Ca, Sn, Al, Mg, P, S; FNb-2 grades increase Ta
Nb, Cr, Ca, Sn, Al, Mg, P, S; FNb-3 grades increase Ta, N, Fe, Si, Ni, Cr, W,
Mo, Ti, Mn, Cu, Ca, Sn, Al, Mg chemical composition requirements.
This standard is proposed by the National Committee for Standardization of Nonferrous Metals (SAC/TC243).
