The video below will illustrate what happens when steel is damaged or bent.
This video demonstrates how the breakdown of metal occurs and how collisions may affect the degree of uniformity. You will get a bump inside your material which was bent when you don’t have any training. This is called work hardening. Only with the proper skills and knowledge can you straighten out the material without creating work hardening. You will create even further problems and can’t fix it. 5k2xul8ker.
