However, as a new technique, an injection molding method has been attempted to improve the working environment and increase the forming efficiency. I have. By the way, in order to obtain a highly reliable Mg injection molding machine, screws and cylinder members for the injection molding machine must be able to be used stably for a long period of time, and the following conditions are required.

定した性能を示している。[0003] 1) The material must have little erosion upon contact with molten Mg. 2) A material that has a high high-temperature hardness when heated to an injection molding temperature of 600 to 650 ° C. of molten Mg and is not easily damaged by abrasion. 3) As a structural member such as a screw or a cylinder, a material having high-temperature strength that is not easily subjected to tempering softening even when heated at the high temperature for a long time. That is, it is a necessary condition that a screw or a cylinder member that comes into intense contact with molten Mg has little erosion (corrosion damage due to molten Mg) and has excellent high-temperature strength and softening resistance during high-temperature heating. As a material having the above-mentioned characteristics, Fe-based tool steel such as JIS standard SKD61 shows almost stable performance.

問題がある。[0005] For example, Inconel (trade name, hereinafter the same) 718 is known as a material having excellent high-temperature strength. However, it is difficult to use it as a material for an injection molding machine due to remarkable erosion by molten Mg. In addition, stellite (trade name, the same applies hereinafter) and other Co base materials generally used as a tool material and a valve material are materials having excellent high-temperature strength. It has been found that the amount is small, but there is a problem that it is difficult to use as a material for an injection molding machine because the toughness is slightly inferior and expensive.
