Abstract
PURPOSE:To improve the strength, ductility, fracture toughness and delayed fracture of the titled steel by incorporating specific amounts of Ni and Ti to the steel and compositely incorporating specific amounts of Nb and B into the same, thereby permitting the industrial application of a nonrecrystallization solution heat treatment in the steel. CONSTITUTION:The steel contg., by weight, 17-26% Ni, furthermore contg. compositely 0.05-0.7% Nb and 0.0005-0.0050% B and consisting of the balance Fe with inevitable components pertaining to steel manufacturing is prepd. By this constitution, the recrystallization temp. is risen and the industrial application of a noncrystallization solution heat treatment is permitted to obtain the Fe-Ni- Ti maraging steel. Said steel is useful in the field of the outer shell material such as a rocket motor case and a pressure container, rollers and shafts.
