摘要：
The present alloys of iron-nickel-chromium-molybdenum system are alloys having high strength and ductility, comprising 0.03-0.2% by weight of carbon, not more than 2% by weight of silicon, not more than 2% by weight of manganese, 42-70% by weight of nickel, 15-35% by weight of chromium, 4.5-15% by weight of molybdenum, 0.05-1.0% by weight of at least one of Ti and Nb as additive elements, and 7.5-35% by weight of iron, the balance being incidental impurities, or further contain 0.1-10% by weight of at least one of tungsten and cobalt as reinforcing elements.
