What is 18/10 Stainless Steel?
Definition and Characteristics
18/10 stainless steel is a strong metal mix made of iron, chromium, and nickel. The name comes from its makeup—18% chromium and 10% nickel. Chromium helps stop rust, and nickel makes it stronger and shiny. This mix makes it tough, safe, and great for food use.
Books on materials science say 18/10 stainless steel also has small amounts of manganese, silicon, and carbon. These extra parts make it stronger and last longer. For instance, chromium is between 17.5% and 19.5%, and nickel is between 8% and 10.5%.
| Element | Percentage Composition |
|---|---|
| Iron | 66.7–71.2 |
| Chromium | 17.5–19.5 |
| Nickel | 8–10.5 |
| Manganese | 2 |
| Silicon | 1 |
| Carbon | 0.07 |
This exact mix keeps 18/10 stainless steel strong, even with heat or acidic foods.
How It Differs from Other Stainless Steel Grades
18/10 stainless steel is different because it has more nickel. Compared to 18/8 stainless steel, which has 8% nickel, 18/10 resists rust better and looks shinier. It also works well with acidic foods, making it great for kitchen tools.
On the other hand, 18/0 stainless steel has no nickel. This makes it less resistant to rust and wear. While 18/0 is cheaper, it’s not as strong or shiny as 18/10.
| Type | Advantages | Disadvantages |
|---|---|---|
| 18/8 | Resists rust, strong, easy to shape | Rusts in saltwater, hardens only with cold work |
| 18/10 | Works with acidic foods, easy to clean, shiny, handles heat well | Costs more, harder to shape, non-magnetic, not ideal for all uses |
| 18/0 | Cheaper, resists rust, good for medical tools | Rusts easier, less shiny |
These differences make 18/10 stainless steel the best for high-quality kitchen tools.
Why It’s a Popular Choice
18/10 stainless steel is common in homes and restaurants because it’s so reliable. It doesn’t rust or wear out, even with daily use. Its shiny look makes cookware and utensils both useful and pretty.
It’s also safe for cooking and storing acidic foods like tomatoes. Its strength and versatility are why 18/10 stainless steel is a favorite for cookware, utensils, and even medical tools.

Composition of 18/10 Stainless Steel
Chromium (18%)
Chromium helps stop rust in 18/10 stainless steel. It makes a thin, invisible layer that protects the surface. This layer fixes itself when it touches oxygen, keeping it strong.
Chromium also handles heat very well. For example:
- 10.5% chromium resists heat up to 700 °C (1,300 °F).
- 16% chromium works at 1,200 °C (2,200 °F).
- 18% chromium resists heat up to 870 °C (1,600 °F).
This makes it great for pots, pans, and tools used with heat or acids.
Nickel (10%)
Nickel makes 18/10 stainless steel shiny and strong. Its 10% content helps stop wear and keeps it polished. Nickel also makes the metal flexible, so it’s easy to shape into kitchen tools.
Unlike cheaper stainless steels, nickel keeps 18/10 stainless steel non-magnetic. This is helpful in places where magnets could cause problems, like hospitals or factories.
Other Elements in the Alloy
Chromium and nickel are the main parts, but other elements help too. Here’s what they do:
| Element | Percentage Composition | Role in the Alloy |
|---|---|---|
| Iron | 66.7–71.27 | Gives strength and structure |
| Manganese | 2 | Makes it harder and less likely to wear out |
| Silicon | 1 | Helps stop oxidation |
| Nitrogen | 0.1 | Adds toughness and strength |
| Carbon | 0.07 | Makes it harder and stronger |
| Phosphorus | 0.045 | Helps with cutting and shaping |
| Sulfur | 0.015 | Improves cutting and shaping slightly |
These parts work together to make a strong, heat-safe, and food-safe material. This mix makes 18/10 stainless steel perfect for homes and professional kitchens.
Key Properties of 18/10 Stainless Steel
Corrosion Resistance
18/10 stainless steel is great at resisting rust and corrosion. The 18% chromium creates a thin, invisible layer on the surface. This layer stops rust and protects the metal from air and moisture. If scratched, it fixes itself by reacting with oxygen around it. This keeps your cookware and tools rust-free for many years.
It also works well with acidic foods like tomatoes or lemons. Unlike other materials, it doesn’t react or break down when exposed to acids. You can safely use 18/10 stainless steel in your kitchen without worrying about rust or stains.
Durability and Strength
18/10 stainless steel is very strong and long-lasting. Chromium and nickel make it tough enough for daily use. Whether it’s cookware, utensils, or tools, this material stays strong under pressure.
Here are some important strength details:
| Property | Value |
|---|---|
| Density | 7.9 g/cm³ |
| Yield strength | 200 MPa |
| Hardness (Rockwell B) | 75 |
| Magnetism | Non-magnetic |
These features show why it’s used for high-quality products. Its hardness prevents scratches and dents. Being non-magnetic makes it useful in places like hospitals or labs.
Heat Resistance
18/10 stainless steel handles high heat very well. Chromium helps it resist heat without bending or losing shape. This makes it perfect for pots and pans used on stoves or in ovens.
For example, cookware made from this material can handle up to 870 °C (1,600 °F). It stays safe and works well even during intense cooking. Plus, it spreads heat evenly, so food cooks consistently without hot spots.
