UNS N06002 Creep rupture Stress Rupture Tests

UNS N06002 is a nickel-based superalloy that is known for its excellent high-temperature strength and resistance to oxidation and corrosion. To evaluate the creep rupture properties of UNS N06002, stress rupture tests are typically conducted.

Stress rupture tests involve applying a constant load or stress to a specimen at high temperatures, typically between 800 and 1200 °C, until the specimen fails. The time to failure is recorded and used to calculate the creep rupture strength of the material.

The test conditions for stress rupture testing of UNS N06002 typically include:

Test temperature: Typically between 800 and 1200 °C, depending on the application.

Test duration: The test can last from several hours to several thousand hours, depending on the desired level of accuracy and the expected service life of the component.

Applied stress: The stress applied to the specimen is typically a fraction of the material’s ultimate tensile strength at the test temperature.

Specimen preparation: Specimens are typically machined to specific dimensions and polished to a smooth surface finish to ensure consistent test results.

Data analysis: The time to failure data is analyzed to determine the creep rupture strength of the material, which is typically reported in terms of stress and time to failure.

It is important to follow established testing standards and procedures, such as ASTM E139, when conducting stress rupture tests on UNS N06002 or any other material.

Here’s a video from C&N about the trialASTM E139 Creep rupture Stress Rupture Tests 17th Sep 2023

At a temperature of 1500°F (816°C), a tensile specimen is subjected to a continuous load of 15.0 Ksi (103 MPa) or higher. The specimen must not rupture within a period of 24 hours. The test is carried out until rupture occurs, without any alteration in the applied load. After rupture, the elongation measured at room temperature must be at least 10% in a gauge length of 4 times the diameter of the specimen (4D). This test procedure adheres to the guidelines specified in ASTM E 139.
