  • Maraging steel
    Patent number: 10378072
    Abstract: The present invention relates to a maraging steel containing, in terms of mass %, 0.10?C?0.35, 9.0?Co?20.0, 1.0?(Mo+W/2)?2.0, 1.0?Cr?4.0, a certain amount of Ni, a certain amount of Al, and V+Nb?0.60, with the balance being Fe and inevitable impurities, in which in a case of V+Nb?0.020, the amount of Ni is 6.0?Ni?9.4 and the amount of Al is 1.4?Al?2.0, and in a case of 0.020<V+Nb?0.60, the amount of Ni is 6.0?Ni?20.0 and the amount of Al is 0.50?Al?2.0.
