430 Stainless Steel | Stainless Steel Supply

430 stainless steel is a type of ferritic stainless steel that contains chromium as its primary alloying element. It belongs to the 400 series of stainless steels, which are known for their excellent corrosion resistance and moderate strength.

In terms of composition, 430 stainless steel contains about 16-18% chromium and less than 0.12% carbon. It also contains small amounts of other elements such as nickel, manganese, and silicon.

430 stainless steel is widely used in various applications such as kitchen appliances, automotive trim, and architectural components. It is particularly popular in the food industry due to its corrosion resistance, ease of cleaning, and low cost.

However, it is important to note that 430 stainless steel is not as corrosion-resistant as some other types of stainless steel, such as 316 or 304. It also has lower toughness and ductility than austenitic stainless steels, which can make it more difficult to form and weld. Nevertheless, 430 stainless steel is a versatile and cost-effective material that is well-suited for many applications.
