What is ASTM B521

The ASTM B521 standard describes the requirements for Tantalum and Tantalum alloys for tubes. These requirements include, among others, the desired chemical composition, mechanical properties such as tensile strength and elongation, and tolerances on dimensions and surface condition.

These standards are applied worldwide to ensure the quality and reliability of Tantalum products within technical applications where performance under pressure is essential. Compliance with these standards forms a basis for consistent product quality, especially when processing into components in industrial environments.
