Nitrox steel: the best choice for your knives

Nitrox steel is an excellent choice for kitchen knives, developed by Ugitech in France and prized for its unique combination of high corrosion resistance thanks to 16% chromium and nitrogen enrichment, which boosts its hardness to around 56-58 HRC (up to 60 HRC depending on the treatment). This "super-stainless" alloy is distinguished by its ease of sharpening and superior edge retention compared to standard steels, making it ideal for intensive use without demanding maintenance. It is often used by cutlers in Thiers such as Tarrerias-Bonjean and Sabatier.

Exceptional corrosion resistance

Nitrogen added to the stainless steel base (iron-carbon-chromium-molybdenum) forms a protective layer more effective than chromium alone against pitting corrosion, food acids, and the constant humidity of kitchens. Unlike carbon steels, which are susceptible to rust, Nitrox remains pristine even after prolonged contact with citrus fruits, salt, or frequent washing, explaining its popularity among professional chefs where hygiene is paramount. This property stems from a fine grain structure obtained through nitriding, which resists oxidation without compromising the blade's flexibility.

Cutting performance and hardness

With a typical hardness of 56-58 HRC (58-60 for the best blades), Nitrox offers a clean, precise edge for meats, fruits, vegetables, or breads, maintaining its geometry longer than X50CrMoV15 thanks to microscopic nitrides that harden the matrix. Its homogeneous microstructure avoids the coarse carbides of conventional steels, allowing for fine cuts without excessive effort or deformation under pressure. Ideal for forged blades such as gyuto or santoku, it balances robustness and finesse, surpassing basic stainless steels in edge retention while remaining less brittle than extreme powders like SG2.

Easy to maintain and sharpen

Despite its hardness, Nitrox sharpens easily on standard stones (1000-3000 grit) at a 15-18° angle, because the nitrogen refines the grit without making it as stubborn as VG10 or SG2. Washing with a soft sponge and immediate drying are all that's needed, without the ritual oiling or fear of stains, making it accessible to both amateur cooks and busy professionals. This simplicity, combined with its impact resistance, makes it a "perfect compromise" for everyday durability without the drawbacks of exotic steels.

French origin and uses

Produced by Ugitech and forged in Thiers (the cradle of French cutlery), Nitrox steel is used in brands such as Sabatier (N4116 Nitro+), Tarrerias-Bonjean (Maestro Idéal), and ETCH , often paired with cherry wood handles for a perfect balance of aesthetics and performance. A symbol of French modernity, it shines in versatile knives (chef's, bread, and paring knives) where durability is prioritized without sacrificing precision. Its growing popularity reflects a quest for locally sourced steels that rival Japanese quality.
