The surface of cold-rolled stainless steel plate is smooth, silver white is the most common, its texture is more delicate and smooth, and the edges are neat; while the texture of hot-rolled stainless steel plate is relatively rough, the shape has no cold-rolled rules, and sometimes the edges are not neat. In addition to the difference visible to the naked eye, what are the other differences between cold-rolled stainless steel sheets and hot-rolled stainless steel sheets?
1. The cold-rolled stainless steel plate is processed by cold rolling, with no scale on the surface and good quality. The hot-rolled stainless steel plate is processed by hot rolling, with scale on the surface and a difference in plate thickness.
2. The hot-rolled stainless steel plate has poor toughness and surface smoothness, and the price is relatively low, while the cold-rolled stainless steel plate has good ductility and toughness, but the price is more expensive.
3. Rolling is divided into cold rolling and hot rolling, with recrystallization temperature as the distinguishing point.
4. Cold rolling is generally used to produce strips, and its rolling speed is relatively high; the temperature of hot rolling is similar to that of forging.
5. The surface of the stainless steel hot-rolled plate without electroplating is dark brown, and the surface of the stainless steel cold-rolled plate without electroplating is gray. After electroplating, it can be distinguished from the smoothness of the surface, and the smoothness of the cold-rolled sheet is higher than that of the hot-rolled sheet.
