Hot Dipped Dx51d Z275 Galvanized Steel Coil SS400 Q235 Carbon Steel Strip

Ss400/Q235 Dx51d Z275 Hot Dipped Galvanized Steel Coil Carbon Metal Plate /Strip
 
Hot rolled steel coil is a kind of smelting material, which belongs to a kind of plate. It is mainly rolled by a continuous hot rolling mill. The hot-rolled sheet finally rolled by the continuous rolling mill can be pickled, annealed, and then rolled into a coil. The hot-rolled sheet in the coil is called hot-rolled steel. roll

Hot rolled steel coil is a technical term for metallurgy. Hot-rolled sheet is a kind of smelting material, which belongs to a kind of plate, and its thickness range is generally specified as 1.2~6mm.1) The cold-rolled sheet is cold-rolled, and the surface has no oxide skin and is of good quality. The hot-rolled sheet is processed by hot rolling, and the surface has an oxide scale, and the thickness of the sheet is poor.
2) The hot-rolled sheet has poor toughness and surface smoothness, and the price is low, while the cold-rolled sheet has good stretchability and toughness, but the price is more expensive.

3) Rolling is divided into cold-rolled and hot-rolled steel sheets, and the recrystallization temperature is the distinguishing point.

4) Cold rolling: Cold rolling is generally used to produce strip, and its rolling speed is relatively high. Hot rolled sheet: hot rolling temperature and forging temperature

5) The surface of the non-plated hot-rolled steel plate is dark brown, and the surface of the non-plated cold-rolled steel plate is gray. After electroplating, it can be distinguished from the smoothness of the surface. The smoothness of the cold-rolled steel plate is higher than that of the hot-rolled steel plate.
