1.4153.03/Niolox/SB1

The Niolox has become a real classic among stainless knife steels. And not without reason. It offers a variety of positive properties that make it the preferred stainless blade steel for some of the most renowned German knife makers.

The Niolox was originally made for cutter knives in the food industry. Based on this area of ​​application, you can already see the main properties of the steel; Corrosion resistance, robustness, edge retention. For a stainless steel, it achieves a high working hardness of a maximum of 62hrc.

It differs from other stainless steels in particular through the addition of niobium. This element forms very hard and small carbides, resulting in high wear resistance and suitability for the finest cutting edges.

Compared to the 1.2695, the Niolox is more robust and better suited for very fine cutting edges. However, the wear resistance is behind that of 1.2695.

Hardening is complex and requires a high hardening temperature and a long holding time. Freezing treatment is also recommended. Unless you have the necessary infrastructure and experience to harden stainless steels, I recommend using the services of a hardening shop.

I myself do not offer a hardening service for the steels I sell. However, I can unreservedly recommend the hardening service of my colleague Jürgen Schanz. He works with a very experienced hardening shop that also carries out demanding heat treatments exactly according to customer requirements. If necessary, contact Jürgen Schanz directly via his contact form.
