Stainless steel is a popular material used in various applications, including cookware, cutlery, and appliances. When shopping for stainless steel products, you may come across the terms “18/8” and “18/10”. These numbers refer to the composition of the stainless steel and can affect the performance and durability of the product. In this article, we will explore the difference between 18/8 and 18/10 stainless steel.
First, let’s define what these numbers mean. The first number, 18, refers to the percentage of chromium in the stainless steel. Chromium is a key element in stainless steel, as it helps to prevent rust and corrosion. The second number, either 8 or 10, refers to the percentage of nickel in the stainless steel. Nickel is also important in stainless steel, as it adds to the corrosion resistance and enhances the overall appearance of the product.
18/8 stainless steel contains 18% chromium and 8% nickel. This type of stainless steel is commonly used in applications where moderate corrosion resistance is needed, such as in cutlery and appliances. It is also easy to maintain and clean.
18/10 stainless steel contains 18% chromium and 10% nickel. This type of stainless steel has a higher nickel content, which makes it more corrosion-resistant and durable. It is often used in high-end cookware and flatware, as well as in medical and laboratory equipment.
Cold working and hot working of 18/8 stainless steel
18/8 stainless steel can be readily broken and formed into different parts. It is also well-curated for stamping, drawing, and heading. Cold working helps to increase the strength of 18/8 stainless steel metal.Hot-working can also be used on 18/8 stainless steel. However, it should not be done for the temperature below 927°C. The most recommended temperature is between 1149 °C-1260 °C.
So, what is the difference between 18/8 and 18/10 stainless steel? The main difference is the nickel content. 18/10 stainless steel has a slightly higher nickel content, which makes it more corrosion-resistant and durable. 18/10 stainless steel flatware also has more of a luster and shine than 18/8, making it the premium choice of flatware for fine dining establishments.However, 18/8 stainless steel is still a good choice for applications where moderate corrosion resistance is needed. Additionally, 18/8 stainless steel is often more affordable than 18/10 stainless steel.
In conclusion, the difference between 18/8 and 18/10 stainless steel lies in the nickel content. 18/10 stainless steel has a higher nickel content and is more corrosion-resistant and durable, while 18/8 stainless steel is more affordable and suitable for applications where moderate corrosion resistance is needed. Both 18/8 and 18/10 stainless steel are commonly referred to as “food grade” stainless steel, meaning they are safe for use in contact with food,When shopping for stainless steel products, it’s important to consider the composition of the stainless steel to ensure that you are getting the right product for your needs.
