The difference between the carbon content of carbon steel castings

Nowadays, with the continuous development of the industry, the demand for carbon steel castings in the market is increasing. They are generally used in mechanical equipment with higher strength, which can improve the performance of the equipment during use and ensure the equipment’s performance. Operating status, but during production, due to different processes, there are many types of castings. Then we will introduce to you what is the difference between low carbon, medium carbon and high carbon in carbon steel castings?

Low carbon has low strength and limited application fields. In the production process, some elements such as manganese, vanadium, titanium, niobium, etc. are added, which can effectively improve the strength of castings.

Under normal circumstances, medium carbon steel contains slightly more carbon and strengthens its strength, but its weldability is poor. Generally, the higher the carbon content, the greater the thickness of the steel plate, and cold cracks are likely to occur during welding.

High-carbon steel is a relatively common type of carbon steel castings. Due to the high internal carbon content, the weldability is poor, but gentle cooling is required during welding to reduce the formation of cracks.
