Series 400 stainless steel is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-saving stainless steel, also known as stainless iron. 400 series stainless steel contains martensitic structure and iron elements, not only has normal magnetic properties, but also has strong resistance to high temperature oxidation, compared with carbon steel, its physical properties and mechanical properties have been further improved. And most 400 series stainless steels can be heat treated.
The commonly used 400 series stainless steel varieties are 430, 410, 420, 409L, etc., of which 430 stainless steel is the most used. The chromium content of 430 stainless steel is 18%, which is characterized by cheap price, small thermal expansion coefficient, chloride stress corrosion resistance better than 300 series stainless steel varieties; However, its shortcomings are also relatively obvious: the formability, weldability and tensile strength are less than 300 series stainless steel models, so the scope of use is limited. 410, 420 stainless steel has a chromium content of 13%, and their main feature is high hardness.
Under the same chromium content, 400 series stainless steel has the same corrosion resistance as 300 series stainless steel in the atmosphere, fresh water and nitricacid oxidizing media, and is better than 200 series stainless steel. Adding trace amounts of niobium, titanium, copper, aluminum and other elements can improve its deep drawing performance, weldability, corrosion resistance and high temperature strength, and can partially replace 300 series stainless steel.
