What is ASTM B391

The ASTM B391 standard describes the requirements for Niobium and Niobium alloys for bars. 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 Niobium 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.
