The Fine Metal Branch of CISRI has the ability to produce master alloy bars of casting superalloys and strips of deforming superalloys, till now, we have a R&D and producing history of more than 50years in superalloy industry.
At present, we have produced the following casting master alloys: K417(IN100), K403, K4169(Inconel718C), K418(INCO713C), K640(X40), DZ40M(DSX40) etc. And the following deforming superalloys: Inconel601, Inconel800, Inconel800H, Inconel718, Rene41, Waspalloy, C263, A286, HA188, GH95 etc.
Product type: Fe-based superalloy, Ni-based superalloy, Co-based superalloy.
We can provide different shape products, like superalloy bar, superalloy rod, superalloy wire, superalloy ingot, superalloy strip, superalloy plate, superalloy tube, etc.
Superalloy is one of our main products. We have a lot of co-operating with foreign companies. Our goal is to produce superalloy materials of specification and designation needed by customers.
Introduction about superalloy:
Superalloys are important metal materials used for hot end parts of modern aerospace turbines, high temperature parts of rocket turbines and equipment in field of energy, metallurgy and chemistry. They can be used under conditions of higher stress, high temperature (600-1100) oxidization atmosphere, combustion and corrosion. According to base element, Superalloys are divided into Fe-base, Ni-base and Co-base alloys. According to formation process, superalloys are divided into deformation alloy, precision casting alloy and powder alloy. The main requirements of superalloy properties are heat-stability, heat-strength and texture stability.
Generally, superalloys are used in combustion chamber, force-added combustion chamber, directional blade, turbine blade and turbine disc. The typical materials used in combustion chamber and force-added combustion chamber are GH3030, GH3039, GH1140, GH333, GH2018, GH42, GH3044, GH3218, GH170, GH163 etc. Directional blade material is mainly casting alloys; The typical alloys are K32, K14, K38, K3, K5, K17, K19, K002, K20 etc. Turbine blade material is mainly age-hardening deforming alloys and casting alloys. The typical working blade material is GH4033, GH2302, GH143, GH4049, GH151, GH118, GH220, K417, K419 etc.
