Yield Strength:
Yield strength or yield point is a material property defined as the stress to which a material undergoes plastic deformation. Before yielding, the material deforms elastically and then returns to its original shape when the stress is removed. Q345B steel has a yield strength of 345 MPa. Like most steel of the same grade, it will stretch before stretching, typically only 20%-21% of the original length.
Tensile strength:
Material tensile strength refers to the maximum tensile stress that a material can withstand when it breaks. The formula for calculating the tensile strength of steel is: the ratio of each force to the cross-sectional area; the metric unit of measurement is Pascal. One Pascal = 1 Newton per square inch (that is, the force of 1 kilogram of material per second to produce an acceleration of 1 m). The tensile strength of Q345B steel is 470~660 MPa (units are million units).
