Product Description

Hot Rolled MS Mild Carbon Steel Coil Q235B Q345B For Building Decoration Construction

Deformation aging is more harmful to the ductility and toughness of low carbon steel than quenching aging, and there are obvious upper and lower yield points on the tensile curve of low carbon steel. From the appearance of the upper yield point to the end of yield extension, a surface corrugation band, called Luders zone, is formed on the surface of the sample due to uneven deformation. Many stamping parts are often scrapped as a result. There are two ways to prevent it. A high pre-deformation method, pre-deformation of steel placed for a period of time after stamping will also produce luders zone, so the pre-deformation of steel before stamping place time should not be too long. The other is to add aluminum or titanium to the steel to form a stable compound with nitrogen that prevents the formation of deformation aging caused by the Collarian gas mass.
