SS 409 Stainless steel pipe tube

SS409 stainless steel is an economical ferritic stainless steel known for its good corrosion resistance, high temperature resistance and low cost. SS409 stainless steel has a low carbon content, usually less than or equal to 0.03%, and a chromium content between 17.0-19.0%. It also contains elements such as manganese, silicon, nickel, phosphorus, sulfur and titanium, and the content of each element is strictly regulated. For example, the carbon content does not exceed 0.08%, the manganese and silicon contents do not exceed 1.00% respectively, and the nickel content does not exceed 0.50%. The yield strength of SS409 stainless steel must be greater than or equal to 175MPa, the tensile strength must be greater than or equal to 360MPa, and the elongation must be greater than or equal to 25%. Due to its good high temperature resistance, SS409 stainless steel is often used in automotive exhaust systems to improve the efficiency of the system and reduce exhaust emissions. In addition, it is also suitable for equipment that requires high temperature resistance, such as household heating furnaces, farm equipment and fuel filters.

SS409 stainless steel pipe is a general-purpose ferritic stainless steel. Its main features include:

Chemical composition: It is mainly composed of iron (Fe), chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), phosphorus (P) and sulfur (S), with a high chromium content, which gives it a certain corrosion resistance.

Corrosion resistance: Although the relatively low content of chromium and nickel makes it less corrosion-resistant than other types of stainless steel, it still has good heat resistance.

Machinability: In most cases, 409 stainless steel pipes need to be preheated before welding, and the preheating temperature is generally between 150 and 260 degrees Celsius. Excessive preheating may seriously damage the metal.

Application areas: Commonly used in non-visual parts in the automotive industry, such as brakes, rotors, pipes and engine components.

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.
