These steels contain 18 % chrome and 8 % to 10 % nickel. They are highly resistant to corrosion that can be caused by cooking salt from leftover food and regenerating salts. Knife blades made of chrome-nickel steel are potentially also rust-and acid-resistant to a high degree, but would easily bend out of shape and would immediately become blunt.  \nKnife blades used to be made of tempered carbon steel which was not resistant to rust. Because of this, hotels used special knife-cleaning machines and polishing pastes to give the knife blades a shiny appearance. To avoid this time-consuming task, the surface of the knife blades were chromeplated.  \nHardenable stainless steel has only been available since 1921. The more carbon (0.3 % to 1.0 %) the steel contains, the harder and more edge-retaining it can be tempered at, but the less rustresistant it becomes. On the other hand, with less carbon, the rust-resistance is better but the edge-retention is worse. With a higher carbon content, lower corrosion resistance is improved by the addition of molybdenum.  \nOur table and kitchen knives are corrosion resistant if maintained properly. Knife blades can suffer and corrode from improper cleaning. Permanent moisture, high salt content in the air or water and acids from food leftovers can all cause corrosion.  \nDue to our lab tests at Victorinox, we can guarantee that only first-class steels are used that meet our high quality requirements. Special alloys are used for various steels, which have matching characteristic features that are essential to each respective application. Before raw materials can be used or processed, they have to pass vigorous testing.  \nA rust-free chromium and molybdenum-alloyed special steel is used for our household and professional knives. Every single delivery of steel to the Victorinox manufacturing facility is analysed and tested to determine which hardening and annealing temperature guarantees the best edgeretaining capacity while preserving a sufficiently high rust-resistance. The hardening process, at temperatures between 1’010°C to 1’060°C (1’850°F to 1’940°F) and the annealing process at temperatures between 160°C to 250°C (320°F to 482°F), makes the blades hard, flexible and edgeretaining.  \nVictorinox sells about 7 million paring, table and household knives annually world-wide. Complaints relating to insufficient rust-and acid-resistance are insignificant, one in every 10'000 knives sold, atthe most.  \nSteel-suppliers  \nEurope-Material type according to SN EN ISO 8442-1: martensitic stainless steel  \n\n| raw material | short name | C | Cr | Mo | V |\n| --- | --- | --- | --- | --- | --- |\n| group | DIN | [%] | [%] | [%] | [%] |\n| 1.4034 | x46Cr13 | 0.43-0.50 | 12.5-14.5 |  |  |\n| 1.4109 | x70CrMo15 | 0.65-0.75 | 14.0-16.0 | 0.40-0.80 |  |\n| 1.4110 | x55CrMo14 | 0.48-0.60 | 13.0-15.0 | 0.50-0.80 | \u003C 0.15 |\n\nVictorinox AG Customer Service November 5 , 2015 Qd-00042_EN","cbCais1YejC1QUme","https://ap.wps.com/l/cbCais1YejC1QUme","pdf",277708,"English","# Stainless steel and corrosion resistance\n## Chrome, nickel, and alloy composition\n## Carbon steel vs chrome-plated knives\n## Carbon content, molybdenum, and performance trade-offs\n## Proper maintenance and common corrosion causes\n## Victorinox steel testing and manufacturing parameters\n## Production scale and customer complaints","[{\"question\":\"What alloying elements make stainless steel tableware and knives corrosion resistant?\",\"answer\":\"They are made of highly alloyed chrome-nickel steels such as 18/8 or 18/10, containing about 18% chrome and 8%–10% nickel.
