ASTM E21 Elevated Temperature Tension Tests of Metallic Materials

ASTM E21 standard test methods cover procedure and equipment for the determination of tensile strength, yield strength, elongation, and reduction of area of metallic materials at elevated temperatures. ASTM E21 standard provides essential guidelines for evaluating the mechanical properties and performance of materials at elevated temperatures and hence providing an estimate of the ability of metals to withstand the application of applied tensile forces.


Introduction to ASTM E21

ASTM E21 establishes standard specifications for conducting elevated temperature tension tests on metallic materials. These tests are crucial in assessing the mechanical behavior and performance of materials under elevated temperature conditions, providing valuable information for material selection, design optimization, and research. Further, ASTM E21 results can be used for giving an indication of probable behavior of the test specimen under other simple states of stress, such as compression, shear, etc. ASTM E21 is widely applicable to industries such as aerospace, automotive, construction, and manufacturing.

The elevated-temperature tension test by ASTM E21 test method assures that the tested material is similar to reference material when other measures such as chemical composition and microstructure also show the two materials are similar. ASTM E21 test method is useful by manufacturers, users, and distributors to ensure consistent quality and reliability in various industries. MaTestLab has the best network of testing labs in the USA to carry out ASTM E21 test for our clients.

ASTM E21 Test Method

The standard provides requirements for testing machines capable of applying tensile loads and controlling temperature during testing. A suitable heating system, such as a furnace or controlled temperature chamber, is used to raise and maintain the temperature to the desired level throughout the test. The ASTM E21 standard includes the following key aspects related to elevated temperature tension testing:

Test ProcedureThe test specimens are placed in the testing apparatus, and the temperature is gradually increased to the desired elevated temperature at a specified rate. Tensile loads are applied to the specimens and strain gauges are used to measure strain during the test, enabling the calculation of stress-strain curves and other mechanical properties.
Data Analysis and ReportingThe test results provide information on key mechanical properties, such as yield strength, ultimate tensile strength, elongation, and reduction in area, at elevated temperatures. The report includes information such as specimen details, testing conditions, and results.

ASTM E21 Specimens

Specimen detailsThe standard uses flat or round specimens, based on the material and testing requirements.
Specimen dimensionsDetailed guidelines are provided for preparing specimens with specific dimensions, including gauge length, width, and thickness.
Specimen preparationSpecimens are prepared by machining, cutting, or sampling.

ASTM E21 Results

ASTM E21 is a widely recognized standard specification for conducting elevated temperature tension tests on metallic materials. By providing comprehensive guidelines for specimen preparation, testing procedures, and result analysis, this standard ensures accurate and consistent evaluation of mechanical properties and performance at elevated temperatures. The values stated in inch-pound units are to be regarded as standard.
