SS409 stainless steel (ferritic stainless steel) has the following characteristics:
Corrosion resistance
It has good resistance to most corrosive media such as acids, alkalis, and salts at room temperature, and remains stable in high temperature environments. However, it should be used with caution in chlorine-containing environments.
High temperature performance
It can withstand repeated heating below 980°C, and still maintain strength and toughness at high temperatures (about 1370-1400°C), which is suitable for high-temperature scenes such as exhaust systems and burners.
Processing performance
It is easy to cut, weld and form. During processing, attention should be paid to cleanliness to avoid contamination. The risk of carbide precipitation during welding is low, which is suitable for complex structure manufacturing.
Mechanical properties
Tensile strength is about 490 MPa, yield strength ≥900 MPa, elongation ≥15%, and it has both strength and plasticity.
Cost and applicability
The cost is lower than that of 300 series stainless steel. It is widely used in scenes such as automotive exhaust systems, building decoration, and chemical equipment, but the surface is easily scratched.

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
