What characteristics does the 400 series stainless steel possess?

The 400 series stainless steel is known for its good corrosion resistance, which sets it apart from other types of stainless steel, particularly the 300 series, which typically has higher nickel content. The 400 series is primarily composed of chromium, which provides a certain level of resistance to oxidation and rust, but it is not as resistant as the higher nickel alloys. This characteristic makes it suitable for applications where moderate corrosion resistance is sufficient, such as in the manufacturing of kitchen utensils, automotive parts, and other products where exposure to moisture and air is a consideration.

Although the 400 series stainless steel can exhibit high strength and can be lightweight depending on the specific application, these attributes are not the defining characteristics. The high nickel content is more relevant to the 300 series stainless steels, while lightweight is not a primary feature associated with this series, as stainless steel in general tends to be heavier than non-alloy metals. Therefore, focusing on its good corrosion resistance accurately captures one of the essential qualities of 400 series stainless steel.
