Abstract

La présente invention concerne un procédé pour fabriquer une tôle en acier résistant à l'abrasion dont la composition chimique comprend, en poids : 0,24% < C < 0,35%; 0% < Si < 2%; 0% < AI < 2%; 0,5% < Si + AI < 2%; 0% < Mn < 2,5%; 0% < Ni < 5%; 0% < Cr < 5%; 0% < Mo < 1%; 0% < W < 2%; 0,1% < Mo +W/2 < 1%; 0% < B < 0,02%; 0% < Ti < 1,1%; 0% < Zr < 2,2%; 0,35% < Ti + Zr/2 < 1,1%; 0% < S < 0,15% ; N <0,03 %, éventuellement de 0% à 1,5% de cuivre ; éventuellement au moins un élément pris parmi Nb, Ta et V en des teneurs telles que Nb/2 + Ta/4 + V < 0,5% ; éventuellement au moins un élément pris parmi Se, Te, Ca, Bi, Pb en des teneurs inférieures ou égales à 0,1%; le reste étant du fer et des impuretés résultant de l'élaboration, la composition chimique satisfaisant en outre les relations suivantes : 0,095% < C* = C - Ti/4 - Zr/8 + 7xN/8 et 1,05xMn + 0,54xNi +0,50xCr + 0,3x(Mo + W/2)112 + K > 1,8, avec K = 0,5 si B > 0,0005% et K = 0 si B < 0,0005%. On soumet la tôle à une trempe, dans la chaude de laminage ou après austénitisation dans un four. On refroidit la tôle à une vitesse de refroidissement supérieure à 0,5°C/s entre une température supérieure à AC3 et une température comprise entre T = 800 - 270xC* - 90xMn -37xNi - 70XCr - 83x(Mo + W/2) et T-50°C; puis on refroidit la tôle à une vitesse de refroidissement à coeur Vr < 1150xep-''' entre la température T et 100°C, ep = épaisseur de la tôle exprimée en mm ; on refroidit la tôle jusqu'à la température ambiante et on effectue, éventuellement, un planage. Tôle obtenue.
