Abstract

The present invention relates to a martensitic free cutting stainless steel, comprising, by weight percent: C: 0.10 to 1.20 %, Si: 0.10 to 2.00 %, Mn: 0.80 to 2.00 %, S: 0.10 to 0.30 %, Cr: 10.5 to 18.0 %, Pb: 0.03 to 0.30 %, Te: 0.01 to 0.10 %, B: 0.0005 to 0.010 %, and O: 0.005 to 0.030 %, with the remainder being substantially Fe and inevitable impurities; contents of P and N are: P: 0.005 to 0.10 %, and N: ≤ 0.050 %; wherein respective formulae of 3.0 ≤ [Mn]/[S] ≤ 15.0, 0.10 ≤ [Te]/[S], and 10 ≤ [S]/[O] ≤ 40 are satisfied; and wherein a sulfide having a circle equivalent diameter of 2.0 µm or more and an aspect ratio of 10 or less is present in a total amount of 0.50 to 10 % by area ratio.
