S235J2 carbon steel plate sheet price is still a pattern of shock adjustment

The main materials of weathering steel are: Q355GNH, 09CuPCrNiA, 05CuPCrNi, Q345NH, Q235NH, Q295NH, S235J2 carbon steel plate sheet, Q275NH, Q355NH weathering steel plate. Weathering steel plate products are widely used in outdoor, indoor decoration, twilight wall decoration and used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing corrosive media in chemical oil equipment.

The fake and inferior S235J2 carbon steel plate sheet, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick S235J2 carbon steel plate sheet steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

According to different purposes, the thin steel sheets are rolled from billets of different materials. Commonly used materials include plain carbon steel, such as S235J2 carbon steel plate sheet, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, and silicon steel for electrical purposes. The thin steel sheets are mainly used in the automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to delivery directly after rolling, there are also pickled, galvanized and tinned thin steel sheets.
