Nitrum®: Sustainable innovation in steel for cutlery
Nitrogen-enriched martensitic steel guarantees maximum performance, durability, and environmental responsibility in Arcos knives.
Nitrum® steel is Arcos’ commitment to technology, sustainability, and cutting excellence. The result of years of research, this exclusive material incorporates nitrogen from the air into its composition, improving hardness, cutting power, and corrosion resistance, while maintaining an ecological approach with no negative impact on the environment.
The unique development and composition of Nitrum®
Nitrum® is a special martensitic stainless steel, developed and registered by Arcos after an intensive R&D process. It complies with the international standard AISI 420, and its main innovation lies in the incorporation of nitrogen (N₂) directly extracted from the atmosphere; the air we breathe contains approximately 75% of this element.
This addition of nitrogen modifies the classic microstructure of steel to form nitrides instead of carbides, providing substantial improvements in the material’s mechanical and chemical properties.
Main benefits and features
-
Ecological and sustainable: The use of nitrogen from the air significantly reduces environmental impact, without generating negative effects on air, water, or soil. Its production involves no mining and generates no waste, making it a planet-friendly solution.
-
Superior hardness: Nitrum® exceeds 55 HRc on the Rockwell C scale, an advantage that represents more than 3 points above the UNE-EN-ISO 8442-1 standard. This increased hardness results in a longer blade lifespan and exceptional resistance to daily wear.
-
Excellent initial cutting power and durability: The innovative microstructure gives Nitrum® improved initial cutting power and superior edge durability, guaranteeing clean and precise cuts for longer, as certified by UNE-EN-ISO 8442-5.
-
Antimicrobial and corrosion resistance: The formation of smaller nitrides with a finer structure replaces traditional carbides, significantly increasing corrosion resistance and preserving hygiene, crucial for both professional and domestic applications.
Professional application and quality guarantee
Thanks to these advantages, Nitrum® becomes the technological benchmark for Arcos knives, meeting the most demanding requirements of professional kitchens and domestic users who prioritize precision, safety and respect for the environment.
Nitrum® es resultado de la investigación continua de Arcos y representa el compromiso de la marca por ofrecer calidad, innovación y sostenibilidad en cada uno de sus productos.

The Arcos forging process, a truly solid knife
Today, the real difference in a knife lies not only in its design or the steel, but in how the heart of the tool—the blade—is crafted. The forging process Arcos has employed for decades is key to creating solid, strong, and robust pieces that withstand the first heavy use and the test of time, whether in kitchens, production lines, or specialty shops. Understanding the value of a forged knife helps explain why so many professionals choose Arcos year after year.
Arcos tempering and annealing: the real reason our knives cut sharper and last much longer
What makes a knife a truly reliable and precise tool isn’t just the choice of material, but how the steel is worked and “treated” to give its all day after day. At Arcos, the tempering and annealing process has been perfected over generations: from medieval forges to today’s industrial furnaces, we remain committed to quality and rigor. This is how we nurture the heart of every knife for the Horeca sector, industry, and specialized retail.
Why choosing ISO 9001 certified professional knives brings you quality, guarantee and reputation
When you buy professional knives for your business—whether you’re in purchasing, quality control, operations, the central kitchen, or a specialty retailer—you’re looking for more than just attractive or competitively priced products. You’re looking for proven quality, visible certifications, auditable processes, and suppliers who can provide long-term support. That’s why working with an ISO 9001 certified manufacturer like Arcos makes all the difference and is key to your reputation and peace of mind with customers and during audits.
