Venosta makes forks and spoons out of stainless steel, since the properties of this material are perfect for making cutlery. Stainless steel, in fact, is very hygienic and has perfect properties in terms of resistance to corrosion and high temperatures. Stainless steel has a low percentage of carbon and contains about 10% chrome. The addition of chrome is what gives steel its property of stainlessness and corrosion resistance.
The chrome contained in steel is what produces an adherent, invisible and corrosion-resistant film that covers the surface. When cut or damaged, this film is self-repairing. The properties of stainless steel can be heightened by raising the percentage of chrome and adding in other elements, like molybdenum and nickel. 3V Venosta uses two labels of stainless steel, AISI 430 and AISI 304.

DESCRIPTION Stainless steel 304 is the most common type of stainless steel. This steel is an austentic stainless, non-magnetic in the annealed state, slightly magnetic if cold-formed. It is non hardenable. It can be hardened by cold deformation. This steel has good mechanical properties. Its mechanical properties are not high at ambient temperatures, in fact, but are best at very low temperatures, in particular in terms of resilience and high fatigue resistance with low sensitivity to notching. USES This kind of steel is used to produce household accessories; kitchen utensils and cutlery. It is also used to produce equipment for the processing and preservation of foodstuffs and in the chemical, pharmaceutical, textile and oil industries. Lastly, we find it being applied in architectural and automotive decorations and the interior design sector. RESISTANCE TO CORROSION In its solubilized state, this type of material is resistant to corrosion by a wide variety of substances involved in the chemical, textile, oil, dairy and foodstuffs industries. RESISTANCE TO OXIDATION Stainless steel 304 has good resistance to oxidation up to 925°C (under conditions of continuous use) and up to 870°C (under conditions of intermittent use). PROPERTIES Specific electric resistance at 20°C: 0.73 ohm × mm²/mm
Thermal conductivity at 20°C: 15W/(m × K)
Specific heat at 20°C: 500 j/(Kg × K)
Thermal expansion between 20°C and 300°C: 17 × 10-6m / (m × K)
Thermal expansion between 20°C and 500°C: 18 × 10-6m / (m × K)
Magnetizability: Possibility of weak presence in cold-formed materials

DESCRIPTION Ferritic, ferromagnetic stainless steel. Non hardenable. Hardenable by cold forming (rolling, drawing, etc.) to obtain increases in the mechanical strength properties. USES This kind of steel is used to produce household accessories; kitchen utensils and cutlery, and the manufacture of valves. It is also used in the automobile industry, for household appliances and in the chemical industry. RESISTANCE TO CORROSION This type of material has good corrosion-resistant properties at ambient temperatures as well as higher temperatures.
Stainless steel 430 also has perfect properties under the average corrosive conditions (atmospheric and, most importantly, frequent cleaning; fresh water; organic compounds, petroleum and phenol; household detergents, foodstuffs, weak organic acids, various alkalis). RESISTANCE TO OXIDATION Stainless steel 430 has a good resistance to oxidation up to 700°C (under conditions of continuous use) and up to 800°C (under conditions of intermittent use). PROPERTIES Pecific electrical resistance at 20°C: 0.65 ohm × mm²/mm
