ASTM B393 Niobium Plate

Description of ASTM B393 Niobium Plate

The niobium plate as outlined in ASTM B393 is a niobium plate of the highest purity manufactured as per ASTM B393, which defines the chemical composition and mechanical properties, dimensional tolerances, surface quality, and method of controls/inspections of a niobium plate, thus fostering reliable and uniform product quality. This plate is not a simple piece of metal. Rather, it is a specially engineered piece of metal that has undergone complex procedures, which is coupled with extensive quality assurance. Such metal is extremely useful in a myriad of industries that have mathematically stringent material performance criteria.

When it comes to properties of the plate, ASTM B393 niobium plate starts as niobium in the purest form and, as a result, is of the highest purity. 99.95% niobium is the minimum requirement, and to a lesser extent, oxygen, nitrogen, carbon, and iron are acceptable, provided all other standards are met. Such elevated levels of purity are essential in order to maintain ductility, corrosion, as well as performance at elevated temperatures while exhibiting the other properties associated with niobium metal, which are, high melting point and a low thermal neutron absorption cross-section. Having been rolled and annealed, the plate exhibits a uniform grain structure, with mechanical properties that are stable and thus meet the requirements of diverse processing and usage environments.
The ASTM B393 niobium plate has multiple steps to process and test it to standards. Starting with raw material selection, high-purity niobium is produced, and then it is melted by either using a vacuum or an electron beam. The melted niobium is transformed into niobium ingots, and then the ingots are rolled into plates with various thicknesses by the hot and cold rolling processes. During the rolling and annealing process, there are strict limitations which are rolling temperature, deformation, and annealing to eliminate the possibility of the plates having a microstructure. The plates are then put through a variety of processes: flattening, shearing, surface treatment, and then cleaning to make the ASTM B393 niobium plate meet the standard requirements.
