Introduction
38CrSi is a kind of medium-alloy steel which is widely used in industrial engineering and has been accepted by customers who rely on its accumulation of experience and application in industry. It is widely used in axles, pinions, camshafts and other components because of its good strength, impact strength and hardenability.
Chemical Composition and Performance
The 38CrSi steel is composed of carbon (C), silicon (Si), manganese (Mn), sulphur (S), phosphorus (P), chromium (Cr), molybdenum (Mo), nickel (Ni) and other elements. The content of each element is very important, and the most important element is chromium, which can effectively improve the overall performance of 38CrSi steel. In addition, under normalizing or quenching, 38CrSi steel can obtain a high strength and a relatively good toughness. This material also has the characteristics of good hardenability and machinability, but its corrosion resistance is worse than that of stainless steel.
Applications
38CrSi steel is usually made into axles, pins, camshafts and other components to meet the engineering and industrial requirements, due to its good strength, impact strength and hardenability.
In the oil and gas industry, 38CrSi steel is mainly used for oil pipeline flange welded tube and connecting part components, such as the ball shell, and other principle components. In the automotive industry, this steel is mainly used to manufacture the main driving axle of the automobile, as well as the synchronizers and splines.
With the development of society, 38CrSi steel has become increasingly widely used in industrial applications, so that it has become a very popular industrial material.
Conclusion
38CrSi steel is a kind of medium-alloy steel with good strength, impact strength and hardenability. It is mainly used in the engineering and industrial sectors, mainly making axles, pins, camshafts and other components. In addition, it is also widely used in the oil and gas industry and the automotive industry. With its wide application, it has become a very popular industrial material.
