Product Description

 

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%).

Item	Carbon structural steel bar
Introduction	Carbon structural steel bar refers to carbon steel with less than 0.8% carbon.
	This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel,
	and has better mechanical properties. Carbon structural steel can be divided into three categories
	according to different carbon content: low carbon steel (C≤0.25%),
	medium carbon steel (C is 0.25-0.6%) and high carbon steel (C>0.6%).
	According to different manganese content, carbon structural steel is divided into two groups:
	normal manganese content (manganese 0.25%-0.8%) and higher manganese content (manganese 0.70%-1.20%).
	The latter has better mechanical properties. And processing performance.
Standard	ASTM, DIN, ISO, EN, JIS, GB, etc.
