409 Stainless Steel Pipe
This is a cost-effective, Titanium-stabilized ferritic stainless steel (magnetic, ≈11% Chromium). It offers good oxidation and heat resistance up to ≈675°C in continuous service, with better corrosion resistance than carbon steel, though it may develop a light surface rust (not for decorative use).Its primary application is the Automotive Exhaust System (mufflers, catalytic converters, tailpipes). Other uses include farm equipment, structural supports, and some heat exchanger tubing where high-temperature resistance is prioritized over aesthetics.
