Mechanical properties of corten steel sheet

Corten Steel Sheet Yield Strength: Yield Strength is the stress corresponding to the plastic deformation of corten steel sheet. The deformation of the corten steel sheet is elastic before the yield point, and it will return to its original shape when the applied stress is removed. When the stress exceeds the yield point, part of the deformation is retained as irreversible permanent deformation. Corten Steel Sheet Tensile Strength: The maximum stress that the specimen will bear before breaking during tension. Usually the tensile strength corresponds to the stress when necking occurs.

Corten Steel Sheet Elongation: elongation, also known as post-break elongation, refers to the percentage of the length of the standard distance increased by the sample after breaking. The larger the elongation is, the greater the permanent deformation that the corten steel sheet can endure before being subjected to mechanical failure, and the better the formability is.

Yield strength, tensile strength and elongation are generally measured by tensile test.

Corten Steel Sheet Impact Work: impact work, or toughness, refers to the work absorbed by a specimen when it breaks under impact during impact testing. The unit is Joule (J). The impact energy shows the corten steel sheet's resistance to impact load. It is measured by Charpy V impact test.
