jominy test
Jominy Test refers to a standard test that is used to determine the hardenability of steel by finding the difference in hardness along the length of a quenched sample.
Key Features:
- Sample Preparation: A cylindrical steel specimen is heated to a prescribed temperature and then placed vertically.
- Water Quenching: One end of the specimen is quenched in water to provide a gradient of hardness along its length.
- Hardness Measurement: Hardness is determined at regular distances along the specimen to determine the hardenability of steel.
Jominy Test is also commonly used in the metallurgical and manufacturing industries for the assessment of steel for heat treatment. It helps identify the appropriate steel for components requiring certain hardness and mechanical properties.
