ASTM E21 - Standard Test Methods for Elevated Temperature Tension Tests of Metallic Materials

ASTM E21 is a set of standardized procedures used to measure how metallic materials behave under tension at high temperatures. Essentially, it assesses the strength and ductility of these materials when heated, which is crucial for applications in industries like aerospace and manufacturing where components may be exposed to extreme heat. The tests provide important information about how materials will perform and endure in real-world conditions, ensuring safety and reliability in their use.
