High performance tool steel produced by powder metallurgy, reaching up to 66 HRc after hardening! Suitable for exclusive knives and knives with a requirement for extreme cutting endurance.

K390 steel is a high performance tool steel produced by powder metallurgy, it is characterized by high toughness even at high hardness. The steel is not corrosion resistant. Together with hardness, wear resistance, i.e. the resistance of the facet, increases. We recommend a cutting angle in the range of 23-26° for maximum blade durability.

Extremely high abrasion wear resistance
Excellent toughness
High compressive strength

Steel is supplied in waterjet cut strips from sheet metal, it is not straightened and corrosion may occur on the surface. The surface is hot-rolled, shaved.
