The paper compares the properties of used and recently designed materials for water turbines blades. Materials are evaluated from standpoint of microstructure, mechanical properties and wear resistance. Stainless steel of type COR13-4 was selected as an initial material. The recently designed materials include heat-treated spheroidal graphite cast iron and vermicular graphite cast iron with modified chemical composition.
