Do you need clarification on the number 18/8 in many advertising posters about stainless steel water bottles? Do you want to figure out the meaning of 18/8? Here I will introduce it in detail.

What is 18/8 Stainless Steel?

First of all, let us know what stainless steel is. Stainless steel is an iron alloy resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, nonmetals, and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from chromium, which forms a passive film that can protect the material and self-heal in oxygen.

18/8 stainless steel is named after the ratio of two vital elements. It refers to 18% chromium and 8% nickel. Chromium's content helps prevent rust and corrosion, while the content of nickel is associated with durability.

18/8 covers a family of stainless steels, including 302, 304, 305, and 384. All these are based on 18/8 stainless steel with other additional elements, among which 304 stainless steel is the most widely used alloy in the AISI (American Iron and Steel Institute) 300 series. 304 stainless steel contains an additional 0.08% carbon on the base of 18% chromium and 8% nickel, which gives this alloy extra strength and hardness. It is commonly used in the dairy, food, and brewing industries.

18/0 vs. 18/8 vs. 18/10 Stainless Steel

As we know from the above explanation, 18/0 stainless steel contains 18% chromium and a negligible amount of nickel. It is much cheaper than 18/10 and 18/8 stainless steel but less corrosion-resistant. It is suitable for everyday cutlery.

18/10 stainless steel contains 18% chromium and 10% nickel with an additional 2% molybdenum. The change in the chromium/nickel ratio and the addition of molybdenum increases the alloy's resistance to chlorides. It's why it is often used in more corrosive environments where the material will be exposed to chemical, solvent, or saltwater corrosion and what makes it the material of choice for marine construction. It is the most durable but also the most expensive.

18/8, 18/0, 18/10 difference

316 is one of the 18/10 family and is the second most popular stainless steel after 304. It is commonly used in the surgical industry, the paper pulp industry as well as in the production of dyes and chemicals.

All in all, 18/8 stainless steel is somewhat less durable than 18/10 but is easier to mold at the manufacturer. In addition, it has the most similar properties to 18/10 and, most importantly, is cheaper. As a result, 18/8 stainless steel stands out from much other stainless steel and is used in many industries, such as healthcare, construction, transport, and restaurants.

18/8 Stainless Steel is Best for Water Bottles

Stainless steel water bottles have been invented for more than 60 years. Through years of development and technological advancement, 18/8 stainless steel has finally become the most popular material for water bottles. It's heat resistant, dust-proof, anti-corrosion, and lightweight, which makes the stainless steel water bottle extremely durable. Most importantly, it is ultra-safe. Hundreds of experiments have proven that high-quality stainless steel is harmless and doesn't emit chemicals into your beverages.

It is also affordable for everyone. Search on Amazon, and you can find thousands of products ranging from a few dollars to tens of dollars. Everyone can find the water bottle they want.

As plastic pollution becomes more and more serious, plastic products are gradually replaced by other recyclable products. Stainless steel water bottles are a great alternative to plastic bottles. It is BPA-free. Using a stainless steel water bottle is also the practice of a sustainable lifestyle and a way to protect our planet. In addition, most stainless steel water bottles are insulated and can keep water warm or cold for hours. It is better than plastic water bottles in every way.

Extend: What is 18/0 Stainless Steel

/0 stainless steel is a type of stainless steel that contains less than 0.5% carbon. This makes it more resistant to corrosion and staining than other types of stainless steel. It is also known for its resistance to heat and ability to maintain strength at high temperatures.

Extend: What is the difference Between /8 and /0 Stainless Steel?

The main difference between /8 and /0 stainless steel is that the carbon content in /8 stainless steel is lower than in /0 stainless steel. As a result, /8 stainless steel is more resistant to corrosion and staining than /0 stainless steel. It can also maintain strength at high temperatures better than /0 stainless steel.

Extend: 18/10 Stainless Steel

Regarding water bottles, the /10 stainless steel designation means that the bottle is made of 18/10 food-grade stainless steel. This is the highest quality stainless steel available, which you'll find in most high-end water bottles. The 18/10 refers to the chromium and nickel content of the steel; 18% chromium and 10% nickel. This combination makes for a strong, corrosion-resistant steel that will last a lifetime. The /10 designation guarantees that you're getting a top-quality product.
