K120C powder steel is a type of steel used in the manufacture of high-quality swords and knives. It is a Japanese steel produced through the powder metallurgy process, in which the steel is turned into powder and then compacted into a desired shape.
K120C is known for its high carbon content, giving it exceptional hardness and edge retention . It also contains other alloying elements such as vanadium, chromium and molybdenum, which further improve its mechanical and corrosion resistance properties .
This type of steel is highly valued by sword and knife makers as it allows them to create sharp and durable cutting blades. However, due to its high quality and the complexity of its production process, K120C powder steel is also typically more expensive than other types of steel used in cutting tool manufacturing.
