Abstract:
A maraging steel strip or part and process for manufacture of a strip or of a part cut out of a strip of cold-rolled maraging steel and hardened by a hardening heat treatment. In the process, before the hardening heat treatment is performed, the strip or the part is subjected to cold plastic deformation with a degree of working greater than 30% and the strip or the part is subjected to recrystallization annealing in order to obtain a fine-grained structure with ASTM index higher than 8. The composition by weight of the maraging steel is: 12%nullNinull24.5%; 2.5%nullMonull12%; 4.17%nullConull20%, Al%null0.15%; Tinull0.1%; Nnull0.003%; Sinull0.1%; Mnnull0.1%; Cnull0.005%; Snull0.001%; Pnull0.005%; Hnull0.0003%; Onull0.001%; iron and impurities resulting from smelting, the chemical composition also satisfying the relationships: 20%nullNinullMonull27%; 50nullConullMonull200; TinullNnull2null10null4.
