Description

Features and Applications


Due to its carbon content range being higher than that of the lowest carbon content carbon steel groups 1006 to 1015, it has the ability to increase strength and hardness as well as reduce cold forming.

During heat treatment, it is recognized as carburized or surface-hardened steel.


Under given quenching conditions, an increase in carbon content can achieve greater core hardness or allow for the use of thicker cross-sections. 

The increase of manganese will improve the hardenability of both the surface and the core. It is the only element in the composition of carbon steel that can increase the surface hardenability. 

Moreover, the higher the content of manganese, the better the mechanical processing performance. 1025 has a low manganese content and good cold formability, and is widely used in the manufacture 

of low-strength bolts.

carbon steel requirement when the silicon content of Si, usually in the following six selected: Si acuities were 0.10%, 0.10% ~ 0.20%, 0.15% ~ 0.35%, and 0.15% ~ 0.4%, 0.20% ~ 0.40%, and 0.30% ~ 0.60%.

When the content of copper (Cu) in carbon steel is required to be specified, Cu should be ≥ 0.2%.

When boron is added to killed steel to enhance its hardenability, titanium is usually added to protect the boron from oxidation. At this point, the boron content is 0.0005 to 0.003%. If titanium is not allowed to be added, 

the boron content can reach 0.005% to enhance hardenability.
