Katalor is a professional steel supplier in China, we export EN10297 C45E seamless steel pipe more than 50,000 ton every month in the world. And most of our customers are from USA, South America, Europe, Africa, Mid-east etc. So that you can believe our EN10297 C45E seamless steel pipe with high-quality, best service and low price. Katalor will introduce the heat treatment process of EN10297 C45E seamless steel pipe for you.
1.Before the EN10297 C45E seamless steel pipe is quenched, the hardness is greater than HRC55 (up to HRC62). The highest hardness for practical application is HRC55 (high frequency quenching HRC58).
2.EN10297 C45E seamless steel pipe should not be subjected to a heat treatment process of carburizing and quenching. After quenching and tempering, the parts have good comprehensive mechanical properties and are widely used in various important structural parts, especially those connecting rods, bolts, gears and shafts that work under alternating load. However, the surface hardness is low and it is not wear resistant. The surface hardness of the part can be improved by quenching and tempering + surface hardening. Carburizing treatment is generally used for heavy-duty parts with surface wear resistance and core impact resistance, and its wear resistance is higher than quenching and tempering + surface hardening. The surface has a carbon content of 0.8--1.2%, and the core is generally 0.1--0.25% (in a special case, 0.35%). After heat treatment, the surface can obtain high hardness (HRC58--62), low core hardness and impact resistance. If carburizing with EN10297 C45E seamless steel pipe, hard and brittle martensite will appear in the core after quenching, and the advantage of carburizing treatment will be lost. Now the materials used in the carburizing process are not high in carbon content, and the core strength can reach 0.30%, which is rare in application. 0.35% has never seen an example, and the process of quenching and tempering high-frequency surface quenching can be used, and the wear resistance is slightly worse than that of carburizing.
