"More case hardened" is a phrase used to describe a material or object that has undergone additional processes of case hardening, resulting in an even stronger, more resilient surface.
Case hardening is a technique commonly employed in metallurgy and materials science to enhance the durability and strength of the outer layer of certain materials, particularly metals or alloys. This process involves introducing carbon or other hardening agents into the surface layer of the material through various methods like carburizing, nitriding, or induction hardening.
When something is "more case hardened," it means that it has been subjected to additional treatment or an extended case hardening process compared to its initial condition. The purpose of this additional hardening is to further strengthen the material's surface, making it more resistant to wear, corrosion, or impact.
In practical terms, the "more case hardened" state generally implies that the material has developed an even higher surface hardness, greater depth of hardened layer, or improved properties like toughness and fatigue resistance. These enhancements can be beneficial in applications where the material is subjected to high-stress conditions, such as heavy machinery components, cutting tools, or bearings.
Overall, the term "more case hardened" denotes an increased level of fortification and durability in the surface layer of a material achieved through additional case hardening processes.
