| GSNb is a patent pending single-phase micro-alloy that has a grain size of approximately 2 ASTM numbers finer than standard commercial grade niobium. Applications: Grain Stabilized Niobium (GSNb) is primarily used for its superior fine grain size while retaining the properties of commercial grade niobium. this allows for reduced "orange peel" during drawing and forming applications, and other applications where a fine grain size is required. It is used extensively in the industrial diamond market. GSNb's corrosion resistance is equal to commercial grade niobium and finds use in the chemical process industry. GSNb can also be used in sputtering targets for fiber optic applications or architectural glass. In nuclear reactors it has low thermal neutron cross-section and superior corrosion resistance. It is an excellent getter and finds use in high temperature vacuum furnaces, and is resistant to attack by the molten alkali metals found in sodium vapor lamps. Forms Available: Foil, Sheet, Plate. Mechanical Properties of GSNb: GSNb meets the mechanical properties requirements of ASTM B393 Type 2 Commercial Grade Niobium (UNS R04210). Corrosion Resistance: The corrosion resistance of GSNb is identical to that of commercial grade niobium and can be used in all applications where commercial grade niobium is used. Like tantalum, GSNb is resistant to most acids with the exception of hydrofluoric, however it is not as resistant as tantalum to strong acids at high temperature. It should not be used with strong bases (alkalis). Information provided by H.C. Starck. |
