Karbon poladının təsviri

Karbon poladı 0.0218% -dən 2.11% -ə qədər karbon tərkibi olan bir dəmir karbon ərintidir. Karbon poladı da deyilir. Ümumiyyətlə, az miqdarda silikon, manqan, kükürd, fosfor ehtiva edir. Ümumi karbon poladındakı karbon miqdarı nə qədər yüksəkdirsə, sərtlik bir o qədər yüksəkdir, möhkəmlik bir o qədər yüksəkdir, lakin plastiklik bir o qədər aşağıdır.

(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 carbon content can be divided into low carbon steel (WC 0.25% or less) to carbon steel, 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.
