High-performance tool steel produced using powder metallurgy, achieving up to 66 HRc after hardening! Suitable for premium knives and knives requiring exceptional cutting edge retention.

K390 steel is a high-performance tool steel produced using powder metallurgy; it is characterised by high toughness even at high hardness.  The steel is not corrosion-resistant. As hardness increases, so does wear resistance, i.e. the durability of the cutting edge. We recommend a cutting angle in the range of 23–26° for maximum cutting edge durability.

Extremely high resistance to abrasive wear
Excellent toughness
High compressive strength

The steel is supplied in strips cut from sheet metal using a water jet; it is not levelled and corrosion may be present on the surface. The surface is scale-covered and hot-rolled.
