Short answer
Check the installed nozzle assembly before buying parts: Creality's current K1 page lists a hardened steel nozzle, an all-metal hotend and 300 °C, but does not say whether that describes the original 2023 K1 or a later revision. Creality asks K1 owners to check for an integrated nozzle before choosing its Unicorn kit, and lists its K1 Series Ceramic Heating Block Kit for the K1.

Questions
Does my Creality K1 have a hardened steel nozzle?
Creality's current K1 page says hardened steel, but it does not say which revision it describes. Check the nozzle assembly installed on your printer before buying parts.[1]
Does the Creality Unicorn kit fit the K1?
Creality lists the Unicorn kit for the K1C, Ender-3 V3 and Ender-3 V3 Plus, and asks K1 and K1 Max owners to check whether their printer has an integrated nozzle before choosing. See K1 nozzles.[2]
