q: Why is stainless steel knife and scissors magnetic?

Answer: Mahalanobis stainless steel should be used to make stainless steel for knives and scissors. Because the knife and scissors have the function of cutting objects, they must have sharpness and hardness. This kind of stainless steel must change its internal structure through heat treatment, and only after increasing the hardness can the knife and scissors be made. However, the internal structure of this kind of stainless steel is tempered martensite, which has magnetoconductivity and can be attracted by magnets. Aoshi stainless steel is non-magnetic, but this kind of stainless steel cannot obtain higher strength by flexible heat treatment. Without strength, it cannot be used to manufacture knife bodies and other purposes such as cookware. Stainless steel determines magnetic or not according to different purposes, so magnetic or not cannot be simply used to explain whether it is stainless steel.

Q: sometimes there are yellow spots after the tool is used?

Answer: stainless steel rust-resistant is related to adding more than 12% chromium into the matrix. In the oxidizing corrosion medium, chromium can quickly generate a dense passivation film on the steel surface to prevent the metal matrix from being damaged. When the chromium content is above 12%, a dense and stable passivation film is formed, and the rust resistance changes in a leap-forward manner, and the corrosion resistance is greatly enhanced, this is why the chromium content in stainless steel should be more than 12%.

As the name implies, stainless steel is non-rusting steel. The "Stainless Steel" here is relative, not absolute, but relative to carbon steel. Stainless steel is not easy to rust, but it is not absolutely non-rust, but in the same conditions and environment, it is not easy to be corroded and rusted compared with carbon steel.

To do a good job of rust prevention for stainless steel knives and scissors, the main reason is not to destroy the passivation film on the surface layer of stainless steel knives and scissors. After using it, clean it as soon as possible and dry it. Try not to contact with acid and alkali salts. After each use, the knives should be washed, dried and smeared with cooked cooking oil, placed in a ventilated and dry place, away from water and gas cookers to prevent rust. If macula occurs, you can clean it with stainless steel special detergent or general toothpaste, wash it with water and dry it for storage.
