MARTENSIC STAINLESS STEEL, MANUFACTURING PROCESS OF A MECHANICAL PART AND MECHANICAL STEEL PART. The present invention relates to a martensitic stainless steel, characterized in that its composition is, in weight percentages as follows: - 9% 243 Cr 243 13%; 1.5% 243 Mo 243; 8% 243 Ni 14%; 1% 243 AI 243 2%; 05% 243 Ti 243 1.5% with Al + Ti 2.25%; dashes 243 Co 243 2%; dashes 243 W 243 1% with Mo + (W / 2) 243 3%; dashes 243 P 243 0 02%; dashes 243 S 243 0.0050%; dashes 243 N 243 0.0060%; dashes 243 C 243 025%; traits 243 Cu 243 0.5%; dashes 243 Mn 243 3%; dashes 243 Si 243 0 25%; dashes 243 0 243 0.0050%; and is such that: @ Ms (198 C) = 1302 - 42Cr - 63Ni-3OMo + 20AI-15W-33mn-28Si-3OCu-13Co + lOTi 242 50 @ Cr eq / Ni eq. 243 1, 05 with Cr eq (%) = Cr + Mo + 5Ti + 5.5AI + 0.6W Ni eq (%) = 2Ni + 0.5Mn + 30C + 25N + Co + 0.3Cu. The present invention also relates to a method of manufacturing a metal part using such steel and the part obtained by such a process.
