The testing results show that: (1) the chemical composition is appropriate with standard, (2) the hardness is 160 HB, (3) the shrinkage is 2.83%. The best casting induction furnace achieved at temperature 1,620☌ as for to the number of ceramic mould coat which is good to be obtained at 7 layers. Based on the experimentation trial implemented on casting products of stainless steel 304, the result indicates that the injection temperature for the wax NF-411 and optimal nozzle in hydraulic injection machine are 64☌ and 30☌, injection pressure 1.75 MPa and injection time 9 seconds. The purpose of this research is to produce a good quality of the casting products as an effort to reduce import dependency of steam turbine blade and to be the alternative way of making steam turbine blades in Indonesia, in addition to the machining process.
