摘要： An investment cast stainless steel article, such as a marine propeller, is composed of a stainless steel alloy containing from 14.5 to 15.2% chromium, 5.35% to 6.05% nickel and 1.0% to 1.5% silicon. During the investment casting procedure, the increased silicon in the stainless steel lowers the driving force for the silicon from reacting with the molten metal, thereby reducing casting defects and decreasing the time and labor required for final grinding and polishing of the propeller
