| 18/10 Stainless | 18% – 20% | 10.0% Min | Austenitic | Surgical / Food Grade |
| 18/0 (430) Steel | 18% | 0% | Ferritic | Magnetic Stainless |
Chromium (18%): Provides the initial layer of oxidation resistance (rust-proofing).
Nickel (10%): Adds deep corrosion protection, high-gloss shine, and non-magnetic properties.
Nickel Content:
As mentioned earlier, 18-10 stainless steel contains 10% nickel, while 304 stainless steel contains 8%.
Why is this 2% nickel so important? Nickel is an expensive metal, and its content directly determines the corrosion resistance of stainless steel. A higher nickel content makes 18/10 stainless steel more resistant to strong corrosive substances such as salt and acid, especially in environments with high chloride content, such as coastal areas.
- Superior Luster and Finish: Nickel is responsible for the “silver-like” glow of stainless steel. Because 18/10 has a higher nickel content, it can be polished to a Grade 8 Mirror Finish that lasts longer and resists dulling even after thousands of industrial wash cycles.
- Enhanced Corrosion Resistance: In environments involving acidic foods (like tomatoes or citrus) or harsh cleaning chemicals, 18/10 is less likely to develop “pitting” or black spots compared to standard 18/8 (304) steel. This makes it the preferred material for Surgical Instruments and High-End Cookware.
- Weight and Density: While the physical weight difference is subtle, 18/10 feels more “substantial” in hand. In the B2B hospitality sector, this perceived quality is vital for brand prestige.
Corrosion Resistance:
18/10 stainless steel is more corrosion-resistant than other types of stainless steel due to its high nickel content. This makes it perform well in wet or acidic environments and is effective in preventing rust and corrosion.
304 stainless steel is equally corrosion resistant, but has a slightly lower nickel content, making 18/10 stainless steel superior in extreme environments.
Wear Resistance:
18/10 stainless steel has high wear resistance and a smooth, scratch-resistant surface. This property makes it ideal for kitchen utensils that are used for a long time and often come into contact with food.
304 stainless steel also has good wear resistance, but it does not perform as well as 18/10 stainless steel under extreme conditions of use.
