Bend Test for Tinplate

The bending test for tinplate is used to evaluate the ductility of tin-coated steel sheets and the adhesion of the coating. The principle involves bending the sample around an axis of a specified diameter and observing whether the surface cracks or the coating peels off. Its purpose is to assess the material's suitability for processing, and it is applied in quality testing for metal products such as cans and packaging containers.
Selection
When selecting, consider the specimen thickness relative to the bending mandrel diameter; for commonly used tinplate with a thickness of 0.17–0.23 mm, choose a mandrel diameter of 1–2 mm. Determine the bending angle according to the standard, typically 180°. Ensure the specimen is free from scratches, and the clamping device should be anti-slip. Maintain the ambient temperature at 23±5℃ with moderate humidity. Record the deformation state of the outer surface after bending.
