摘要

Procedure for the manufacture of a Band or a piece Cut From A Band of Cold Rolled maraging Steel and hardened by Heat Treatment hardening, which prior to the heat treatment hardeningThe Band or the workpiece is subjected to Plastic deformation in Cold Cold smoothie with a ratio exceeding 30% and for the band or the piece to a recrystallization annealing so as to obtain a fine-grained ASTM Index more than 8.The Composition of the maraging Steel comprises by weight: 12% = or = 24.5%, 2.5% Mo = = 12%, 4.17% = co = 20%; The = 0.15%; You = n = 0.1%, 0.003%; if = 0,1%; Mn C = = 0.1%, 0.005% s = 0.001%; p = 0.005% H = 0.0003%; or = 0.001%; the rest being Iron and Impurities resulting from the plastic RationThe chemical composition and satisfying relationships: = 20% ni + Mo = 27%; 50 = co x Mo = 200; ti x n = 2 x 104. Strip or Piece obtained by this procedure and also claimed a Transmission belt and a support Plate Integrated Circuits formed by the band or Piece.
