STAINLESS STEEL HAVING LOCAL VARIATIONS IN MECHANICAL RESISTANCE |
摘要 |
The disclosure mainly relates to a stainless steel sheet containing a minimum of 10.5% by weight of Cr and a maximum of 1.2% by weight of C, the microstructure of which is martensitic or austeno-martensitic and comprises at least 2% by volume of martensite, essentially characterized in that it comprises at least one local portion of lesser mechanical resistance, having a martensitic content at least 10% lower than that of the remainder of said sheet; said local portion being at least partly with a thickness equal to that of said sheet. The disclosure also relates to a method for manufacturing this steel sheet and to a steel part which may be obtained by deformation of this sheet. |
