5wt%とする。Si is an essential element for imparting wear resistance.
If the content is less than 7.5 wt%, this effect will be small, and if the content exceeds 13.5 wt%, a large amount of primary Si will be generated, which will deteriorate the forgeability and mechanical properties, especially toughness and fatigue strength. Getting worse. Therefore, the Si content is 7.5 to 13,
It is set to 5wt%.
