Wiki- Stainless Steel

Stainless steel is an alloy made by adding chromium to increase resistance to rust, which is a major drawback of steel. Although generally inferior to steel in terms of sharpness, stainless steel is not only rust-resistant, but is also strong and chip-resistant, and sharpness lasts longer without frequent sharpening. It is attractive because it is easy to handle and does not require much care. There is a wide range of stainless steel materials, from reasonable ones to high-end ones, and some of them are as hard as steel and are easy to handle and sharp at the same time.

  • “Carbon steel" and “Stainless steel" are the main materials used for knives
  • “Carbon steel" is defined as having 0.02-2.14% carbon content of the five elements of iron. As carbon content increases, the material becomes harder. Cast iron is also used for car parts. Adding more than 10.5% chromium to carbon steel makes it "stainless steel". The addition of chromium improves rust resistance.
