Do you have a question about the application metals in your production process?
What is ASTM B365?
The standard ASTM B365 outlines the requirements for tantalum and tantalum alloys in the form of bars and wires. The specification includes provisions for chemical composition, mechanical properties, dimensions, and surface finish. The material can be supplied in various forms and conditions, including straight or coiled lengths, and is produced through vacuum melting or powder metallurgy processes.
ASTM B365 is applied globally to ensure the reliability of tantalum products within technical environments where chemical resistance, thermal stability, and structural integrity are of paramount importance. The standard provides a clear foundation for consistent product quality in applications operating under high temperatures or in aggressive media.
Tantalum alloys
What is ASTM B365 used for?
Material Properties
Tantalum produced according to ASTM B365 is renowned for its exceptional corrosion resistance, particularly against acids such as nitric acid, hydrofluoric acid, and sulfuric acid. The material has a melting point exceeding 3000 °C and retains its mechanical properties at high temperatures. In alloy form, additional properties can be enhanced, such as increased strength or improved resistance to creep and oxidation. The combination of chemical inertness and structural stability makes tantalum extremely suitable for applications where material integrity is absolutely required.
Industrial Application
Tantalum and its alloys, according to ASTM B365, are utilized in sectors such as the chemical process industry, power generation, semiconductor manufacturing, and aerospace engineering. The material is used in reactor linings, heat exchangers, sputter targets, cathodes, furnace constructions, and as electrically conductive wire in ultra-pure environments. Its mechanical reliability and resistance to thermal degradation make tantalum a strategic material in installations where other metals fall short.
