What is another word for case-hardened steel?
Pronunciation: [kˈe͡ɪshˈɑːdənd stˈiːl] (IPA) 
Case-hardening steel is a popular material used for various applications requiring high strength and durability. It is often referred to as carburized steel, which is a term that indicates the process by which the steel is hardened. Other synonyms for case-hardened steel include surface-hardened steel, nitrided steel, and hardened-and-tempered steel. These terms describe variations in the case-hardening process that are used to achieve different levels of hardness and toughness. For example, nitriding involves exposing the steel to nitrogen gas to form a hard surface layer, while hardening-and-tempering involves heating the steel to high temperatures and then rapidly cooling it to create a hard exterior surface. Regardless of the terminology, case-hardened steel is an excellent choice for applications where strength and durability are paramount.
