On the Necessity of Metal Tensile Test in Precision Stamping Parts Processing Plant

The material strength and plasticity function data obtained from the metal tensile test conducted by the precision stamping parts processing plant are of great application value and reference value for planning and material selection, development of new materials, material procurement and acceptance, product quality control, equipment safety and evaluation.

Metal tensile testing is generally divided into four stages:

1. Elastic stage: As the load is added, the strain is proportional to the stress. If the load is removed, the specimen will return to its original state, showing elastic deformation. During this stage, the elastic modulus of the material can be measured.

2. Yield stage: Ordinary carbon steel: After exceeding the elastic stage, the load is almost unchanged, but it shakes up and down within a small range, and the elongation of the sample increases sharply. This phenomenon is called yielding. 3. Strengthening stage: After the sample has passed the yielding stage, if it is to continue to elongate, the resistance in the sample is continuously increased due to the continuous strengthening of the material during the plastic deformation process. Strain addition stress is also added, and the maximum strength is the limit value of the tensile strength of the metal material.

4. Necking stage: When the strain addition stress decreases, the metal material will undergo a "necking" state until it breaks.

After metal tensile test, a series of mechanical functions such as strength, hardness, fatigue, etc. of the material can be tested. As a precision stamping parts processing plant, only after fully understanding the function of the material can the application environment of the material be safely formulated, and the production can be assured. High-quality and qualified stamping parts can be processed and produced.
