SRIF undertakes the research and development work of special steel material and products in the fields of hydro-power, nuclear power, wind power and sea engineering industries. For many years, the institute has got many achievements in the aspect of research on stainless steel material and casting technology of hydraulic turbine flow parts, which reaches the advance level in the world. The super-low carbon stainless steel developed by SRIF has become the main material in national hydraulic turbine manufacturing industry, and was integrated into the National Casting High Alloy Material Standard.
The production base of special steel castings, which takes 8000 m2, is equipped with 1 set of 5 tons arc furnace, 2 sets of medium-frequency induction electric furnace with capacity of 3 tons and 5 tons respectively, 1 set of 15 tons AOD furnace, several sets of automatic and mixing machines and heat treatment furnaces, 3D laser measuring instrument and modern chemical analysis instruments. It has the production capacity of 4000 tons per year. SRIF has supplied many advanced manufacturing technology and premium castings to large hydropower stations at home and abroad, such as Three-gorge hydropower station. The products were exported to Canada, USA, Japan, Brazil, Spain, France and etc.
