What is the difference between 18/10 and 18/8 stainless steel in terms of their composition and properties?

18/10 stainless steel contains 18 chromium and 10 nickel, while 18/8 stainless steel contains 18 chromium and 8 nickel. The higher nickel content in 18/10 stainless steel makes it more resistant to corrosion and staining compared to 18/8 stainless steel.
