Performance Parameters Of Cold-rolled Steel Sheets

The performance parameters of cold-rolled steel sheets mainly include the following aspects:
Thickness and width: The thickness and width of cold-rolled steel plates are the basic parameters of steel plates, usually in millimeters or inches.
Surface quality: The flatness, smoothness, scale and rust on the surface of cold-rolled steel sheets, as well as whether they have been surface-treated, will affect the surface quality of the steel sheets.
Tensile strength: The tensile strength of cold-rolled steel plate refers to the maximum stress that the steel plate bears in the tensile test, usually in Newton/square millimeter or pound force/square inch as the unit.
Yield strength: The yield strength of a cold-rolled steel plate refers to the stress level at which the steel plate begins to undergo plastic deformation in a tensile test, usually in Newton/mm2 or lbf/in2.
Elongation: The elongation of cold-rolled steel plate refers to the percentage of increase in the length of the sample when the steel plate undergoes plastic deformation in the tensile test.
Chemical composition: The chemical composition of cold-rolled steel sheet refers to the content of various chemical elements in the steel sheet, such as carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel, copper, etc. The difference in chemical composition will affect the performance and use of the steel sheet .
