Stainless Steel: What Is It and Types of Stainless Steel
Stainless steel is an alloy of iron, chromium and other elements. It is one of the most popular materials when it comes to producing a variety of products such as tools, kitchen appliances, automotive components and more. Its popularity is due to its durability and corrosion resistance. The chromium in stainless steel alloy forms an oxide layer on the materials surface which prevents further corrosion and prolongs the materials life.
There are many different types of stainless steel available on the market. The type you choose will depend on the products purpose and budget. Each type of stainless steel is composed of different alloying elements and grades. This makes stainless steel both highly versatile and cost effective. Here is a look at the common types of stainless steel and the grades available.
Type 304 Stainless Steel
This is the most popular type of stainless steel and is also referred to as A2 or 18/8 stainless steel. It is composed of 18% chromium and 8% nickel and has excellent corrosion resistance. It is one of the most common alloys used in the production of kitchen appliances, food processing equipment and medical equipment.
Type 316 Stainless Steel
This type of stainless steel is characterized by its high chromium and nickel content and is referred to as marine grade stainless steel. Its higher level of corrosion resistance makes it well suited for applications that are constantly exposed to harsh salt water and other highly corrosive conditions. Some examples include shipbuilding, water pipes and chemical processing.
Type 410 Stainless Steel
This type of stainless steel is a low-cost alternative to type 304 and is characterized by its high machinability. While it is relatively soft, it is not as corrosion resistant as the other two types. This type of stainless steel is typically used in applications that do not require a high level of corrosion resistance such as kitchen cutlery and machine screws.
Type 420 Stainless Steel
This type of stainless steel is often referred to as “cutlery steel” due to its use in producing kitchen cutlery. It is composed of 12% chromium and is considered to be highly corrosion resistant. It is often used in the production of blades, blades and kitchen knives.
These are the four most common types of stainless steel available on the market. Each type has its own characteristics and is used for different applications based on its grade. To ensure you are getting the highest quality stainless steel for your project, you should consult with a professional or research the grades of stainless steel available before making a purchase.
Stainless steel is a popular material for a wide range of projects due to its durability, its resistance to corrosion, and its range of grades for different applications. While it may require a bit of research and consultation, it is definitely worth the time if you are looking for a quality product that will last for years to come.
