Tensile strength is the maximum amount of pulling or stretching stress that steel or another material an withstand without breaking. This test is conducted by using the Tensile Test, which is covered in a previous definition. The results are a key indicator of a material's overall strength and durability, which is then used to assess its performance. This information can be used by engineers and metallurgists to assign different use cases based on the results to ensure the material will behave under the required tension for that application.
