  • The study was performed to search on alternative material for turbopump parts made of Russian material by analyzing and comparing chemical and mechanical material properties. Iron base material was generally used for turbopump. This material can be categorized into stainless steel and heat resisting steel by quantity of additional elements. Each steel was also classified into austenite steel, ferrite steel, and martensite steel. Alternative materials for turbopump inducer, impeller and casing are chosen by JIS SUS 631 and 321 as a result of this study. Because the material of Russian turbopump turbine may be developed by Russia itself, alternative material can be hardly found. However, Inconel 718 for turbine material is thought to be proper in the aspect of hardness considering general use of this material for turbopump turbine in Japan and France.
