Introduction to Types of Low Carbon Steel

1. Carbon steel can be divided into three categories based on its use: carbon structural steel, carbon tool steel, and free cutting structural steel. Carbon structural steel is generally divided into two types: engineering construction steel and machine manufacturing structural steel;
2. According to the smelting method, it can be divided into open hearth steel and converter steel;
3. 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);
4. 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%) according to its carbon content;
5. According to the quality of steel, carbon steel can be divided into ordinary carbon steel (with high phosphorus and sulfur content), high-quality carbon steel (with low phosphorus and sulfur content), high-grade high-quality steel (with lower phosphorus and sulfur content), and special grade high-quality steel.
