Hot/Cold Rolled Steel Plate/Sheet for Building

Carbon steel is divided into carbon structural steel, carbon tool steel, and free-cutting structural steel. Carbon structural
steel is divided into engineering construction steel and machine manufacturing structural steel;
According to the smelting method,it can be divided into open hearth steel and converter steel; According to the deoxidation method, it can be divided into boiling steel (f), killed steel (z), semi-killed steel (b) and special killed steel (TZ); According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%) and high carbon steel (WC > 0.6%).

1. The use of ordinary carbon steel: This type of steel has a wide range of applications, most of which are used for welding, riveting or bolting steel structural parts, and a few are used for making various machine parts. 2. Characteristics of ordinary carbon steel: Compared with high-quality carbon steel, it has wider restrictions on carbon content, performance range, and content of phosphorus, sulfur and other residual elements. 3. Overview of ordinary carbon steel: Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. The carbon content is less than 0.38\%, and less than 0.25\% is the most commonly used. Belonging to low-carbon steel, each metal grade indicates the lowest yield point of the steel when the thickness is less than 16mm
