18/10 Stainless Steel
Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
What is the difference between 18/8 and 18/10 stainless steel?
The first number is the amount of chromium that is contained in the stainless, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material.
What makes stainless steel corrosion resistant?
To be stainless steel the composition needs to contain at least 10.5% chromium. At this level (and higher) a complex chrome iron oxide is formed instantaneously, that prevents the diffusion of oxygen through this layer and protects the iron matrix from "rusting". This is often called the passive condition or passivated condition.
The nickel content gives it a bright polished appearance and increases its corrosion resistance.
*Chro•mi•um:
A hard metallic element: a hard bluish white metallic element. Uses: Alloys and electroplating to increase hardness and corrosion resistance.

Stainless Steel Cookware:
In stainless steel cookware, the thickness is generally referred to in millimeters, perhaps because of the influence of imports in this category. The standard for top of range stainless steel cookware is 0.6 MM for bodies and lids. Premium department store brands will have stainless steel bodies and lids in the range of 0.7 MM to 1.0 MM thick. Low end stainless steel cookware and low end mixing bowls and accessories are generally 0.5 MM thick.
