Abstract

Acier inoxydable ferritique à usinabilité améliorée utilisable notamment dans le domaine du décolletage, caractérisé en la composition suivante:

C < 0,17 %
Si < 2,0 %
Mn < 2,0 %
Cr [11 - 20] %
Ni 1,0 %
S > 0,55 %
Ca > 30 10-4 %
O > 70 10-4 %
le rapport entre la teneur en calcium et en oxygène Ca/O étant 0,2 Ca/O 0,6, ledit acier étant soumis, après laminage et refroidissement, à
un traitement thermique de recuit lui conférant une structure ferritique.
