STAINLESS STEEL POWDER FOR SINTERING, GRANULATED POWDER FOR MANUFACTURING SINTERED STAINLESS STEEL, AND SINTERED STAINLESS STEEL

摘要

PROBLEM TO BE SOLVED: To provide a sintered stainless steel having a high sintered density.;SOLUTION: An objective stainless steel powder for sintering is manufactured from a molten metal with an alloy composition containing Fe as a main component, containing a predetermined amount of C, Si, Mn, Cr, and Ni, containing 5.0% or less Mo, 5.0% or less Cu, 0.4% or less N, and 0.3% or less S, further containing 2.0% or less Ti, and 2.0% or less Nb, and has 40 μm or less of an average particle diameter, and 6 [%] or more of a F value defined in the equation (I): F [ % ] =-0.0816×(Cr_eq)²+5.975×(Cr_eq)+0.0587×(Cr_eq)×-(Ni_eq)-3.786×(Ni_eq)-46.23...(I), (wherein Cr_eq [%]=(Cr%)+1.5×(Si%)+(Mo%)+0.5×(Nb%), and Ni_eq [%]=(Ni%)+30×(C%+N%)+0.5×(Mn%)).;COPYRIGHT: (C)2003,JPO
