XC45 Lost Wax Investment Casting
XC45 lost wax investment casting is generally used for heavy-duty parts with surface wear resistance and core impact resistance. Its wear resistance is higher than that of quenching and tempering + surface quenching.

XC45 is a French steel number, which is carbon steel.
XC45 execution standard: NF A36
Things to note when using:
1. Before construction in humid sites, dry the welding rod at 150-200°C for 30-50 minutes.
2. It is usually preheated to above 200°C and air-cooled after welding. It is best to perform stress relief if possible.
3. Where multi-layer surfacing is required, use CMC-E30N as the base to obtain better welding results.

Carburizing treatment
XC45 lost wax investment casting is generally used for heavy-duty parts with surface wear resistance and core impact resistance. Its wear resistance is higher than that of quenching and tempering + surface quenching. Its surface carbon content is 0.8--1.2%, and the core is generally 0.1--0.25% (0.35% is used in special cases). After heat treatment, the surface can obtain high hardness (HRC58--62), the core hardness is low, and it is impact resistant.
If No. 45 steel is carburized, hard and brittle martensite will appear in the core after quenching, losing the advantages of carburizing. The carbon content of materials using carburizing technology is not high, and the core strength can reach very high up to 0.30%, which is rare in applications. 0.35% have never seen any examples and are only introduced in textbooks. The process of quenching and tempering + high-frequency surface quenching can be used, and the wear resistance is slightly worse than carburizing.
