409L stainless steel belongs to the ferritic stainless steel series, and its main chemical composition includes chromium (Cr), nickel (Ni), titanium (Ti) and a small amount of carbon (C), silicon (Si), manganese (Mn) and so on. Among them, the content of chromium element is high, giving 409L good corrosion resistance; The resistance to intergranular corrosion can be effectively improved by adding proper amount of titanium element. The lower nickel content makes 409L more economical than other stainless steel types and suitable for large-scale industrial production applications.
Strength and toughness: It has a high yield strength and tensile strength, while maintaining good toughness, can withstand large mechanical stress and impact loads.
Corrosion resistance: Excellent oxidation resistance and resistance to general corrosive media (such as water, air, weak acid, weak alkali, etc.), so that it can maintain good performance stability in a variety of environments.
Thermal stability: under high temperature environment, it can still maintain good organizational stability and mechanical properties, suitable for the process that requires heat treatment.
Due to its economical, practical and excellent performance characteristics, 409L industrial seamless pipes are widely used in many fields:
Automotive industry: As the main material of automobile exhaust system, such as exhaust pipe, muffler and other components, because of its high temperature resistance, corrosion resistance and excellent performance.
Home appliance industry: In the manufacturing of home appliance products such as water heaters and washing machines, it plays an important role as a key material for connecting pipes, heat exchangers and other components.
Chemical equipment: In the chemical industry, as a pipeline system for conveying corrosive media, this seamless pipe has been widely used for its good corrosion resistance.
Other fields: It can also be used in construction, Bridges, machinery manufacturing and other fields as raw materials for structural parts or functional parts.
