Abstract

A precipitation hardening stainless steel powder, containing Cr at a concentration A within a range of 15.00 mass % or more and 17.50 mass % or less, Si at a concentration B within a range of 0.30 mass % or more and 1.00 mass % or less, Nb at a concentration C within a range of 0.15 mass % or more and 0.45 mass % or less, Ni at a concentration D within a range of 3.00 mass % or more and 5.00 mass % or less, Mn at a concentration E within a range of 0.05 mass % or more and 1.00 mass % or less, and Cu at a concentration F within a range of 3.00 mass % or more and 5.00 mass % or less, wherein a value of δ defined by the following formula (1) is 10.0 mass % or more and 14.0 mass % or less. δ=3(A+1.5B+0.5C)−2.8(D+0.5E+0.5F)−19.8  (1)
