This investigation seeks to improve on the mechanical property of yield strength, while maintaining 10% elongation prior to fracture observed with of Custom 450 stainless steel in an air-melted investment casting operation. Improving this performance includes an additional heat treatment step of homogenization, as well as replacing the alloy. After identifying and downselecting available high strength stainless steels, a trial of Custom 455 stainless steel is recommended due to its high strength compared to the other alternative alloys. A trial has been developed to analyze the effect air melting has on the chemical composition and mechanical properties of Custom 455 stainless steel.
