Cold Rolled Carbon Steel Coil DX51D Q235 Steel Coil For Building Materials
1 Classification Introduction
(1) according to the use of carbon steel can be 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 two
kinds;(2) according to smelting method, it can be divided into open
hearth steel and converter steel;(3) According to the deoxidation
method can be divided into boiling steel (F), killed steel (Z),
semi-killed steel (B) and special killed steel (TZ);(4) according
to the carbon content, carbon steel can be divided into low carbon
steel (WC ≤ 0.25%), medium carbon steel (WC0.25% - 0.6%) and high
carbon steel (WC> 0.6%).(5) according to the quality of
steel, carbon steel can be divided into ordinary carbon steel
(containing phosphorus, sulfur is higher), high quality carbon
steel (containing phosphorus, sulfur is lower) and high quality
steel (containing phosphorus, sulfur is lower) and super high
quality steel.
