Abstract
In a method for manufacturing a stainless steel die cast product having low melting point, an alloy consisting of 0.01-0.1% by weight of carbon, 1.0-3.0% by weight of silicon, not more than 12% by weight (but excluding 3-7% by weight) of manganese, 8-25% by weight of nickel, 16-20% by weight of chromium, 1.5-2.5% by weight of copper, 0.2-0.7% by weight of boron, 0.5-2.0% by weight of molybdenum and the balance of iron is die-casted in a metal mold made of a tungsten alloy or a molybdenum alloy and maintained at a temperature of the metal mold of 250.degree.-450.degree. C. under conditions of a casting temperature higher than the liquid phase temperature of the molten alloy by 100.degree.-150.degree. C., an injection pressure of 200-500 kg/cm.sup.2, and an injection plunger speed of 0.2-1.0 m/sec.
