The more carbon dissolved in austenite, the higher the hardenability. it has little to do with alloy elements. The hardenability is closely related to the alloying elements.
Steel with high hardenability may not necessarily have high hardenability.
2. Application of Hardenability in Production

When the performance in the parts list can be inconsistent (without requiring quenching), steel with suitable quenching properties can be selected. Such as gears;
Steel with high hardenability should not be used for welding components, otherwise quenching structure may appear near the weld seam, causeusing deformation and cracks;
For steel with good hardenability, a quenching medium with a slow cooling rate can be used. This is very advantageous for complex workpieces. [4]
