DIN 15CrMo3 DIN 17155-2 Steel Plate
astm pressure vessel Product Introduction
In the automotive industry, DIN 15CrMo3 DIN 17155-2 steel is used to produce components and parts such as crank cases, heat shields, exhaust systems and other automotive parts that require high strength and corrosion resistance. In addition, it is also used in the production of agricultural machinery, construction equipment, mining machinery and many other industrial components.

DIN 15CrMo3 DIN 17155-2 Mechanical Properties
Yield strength is the yield limit of DIN 15CrMo3 DIN 17155-2 when yielding occurs, that is, the stress resisting micro-plastic deformation. The external force greater than the yield strength will make the DIN 15CrMo3 DIN 17155-2 parts permanent failure and unable to recover. Less than this, the DIN 15CrMo3 DIN 17155-2 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 DIN 15CrMo3 DIN 17155-2 under static tension. Tensile strength is the resistance that characterizes the maximum uniform plastic deformation of DIN 15CrMo3 DIN 17155-2. The deformation of tensile specimens is uniform before they bear the maximum tensile stress, but beyond that, the DIN 15CrMo3 DIN 17155-2 begins to neck, i.e. concentrate deformation.
