The "grade" of stainless steel refers to its quality, durability and temperature resistance. The numbers (18/8, 18/10, etc.) are the composition of the stainless steel and refer to the amount of chromium and nickel (respectively) in the product.
18/8 and 18/10: These are the two most common grades of stainless steel used for food preparation and dining, also known as Type 304 (304 Grade) and are part of the 300 series. The first number,18, refers to the amount of chromium present and the second represents the amount of nickel. For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel.
304 grade stainless steel is also comprised of no more than 0.8% carbon and at least 50% iron. The chromium binds oxygen to the surface of the product to protect the iron from oxidation (rust). Nickel also enhances the corrosion resistance of stainless steel. Therefore, the higher the nickel content, the more resistant the stainless steel is to corrosion.
When it comes to flatware, people often assume that 18/10 is heavier in weight. Actually, there is no difference between 18/8 and 18/10 flatware when it comes to weight. The additional nickel in 18/10 flatware makes it a bit sturdier (meaning the tines of a fork are slightly more difficult to bend back and forth). The additional nickel also lends itself to a shinier surface. 18/10 Grade of Stainless Steel is the highest Grade of Stainless Steel for any Cutlery and Kitchenware
