Chemical and Mechanical
Yield strength is the yield limit of GB CM690 GB/T 18669 when yielding occurs, that is, the stress resisting micro-plastic deformation. The external force greater than the yield strength will make the GB CM690 GB/T 18669 parts permanent failure and unable to recover. Less than this, the GB CM690 GB/T 18669 parts will return to their original shape.
Tensile strength is the critical value of transition from uniform plastic deformation to locally concentrated plastic deformation. It is also the maximum load-carrying capacity of GB CM690 GB/T 18669 under static tension. Tensile strength is the resistance that characterizes the maximum uniform plastic deformation of GB CM690 GB/T 18669. The deformation of tensile specimens is uniform before they bear the maximum tensile stress, but beyond that, the GB CM690 GB/T 18669 begins to neck, i.e. concentrate deformation.
