- Bluing steel is a passivation process that partially protects steel against rust using a black oxide coating1. There are different methods for bluing steel, including:
- Cold bluing: Applying a protective layer of oxide on the surface of the steel to repel moisture and prevent oxidation.
- Hot bluing: Heating the steel to a high temperature and quenching it in oil or water to create a deep, blue-black color and improve durability and corrosion resistance2.

It is named after the blue-black appearance of the resulting protective finish.en.wikipedia.org/wiki/Bluing_(steel)Hot bluing is a process that involves heating the steel to a high temperature, typically around 550°F (290°C), then quenching it in oil or water. This process creates a thin layer of oxide on the surface of the steel, which gives it a deep, blue-black color. The layer also improves the steel’s durability and resistance to corrosion.forgingworld.com/bluing-steel-with-a-torch/ 4 Ways to Blue Steel - wikiHow
