MERIH STAINLESS, based in Istanbul, Turkey, has made a name for itself as a top-notch manufacturer and supplier of high-quality stainless steel products, delivering robust solutions for both industrial and commercial needs. One of their standout products, Stainless Steel 409 Pipes, is designed to perform exceptionally well in environments with moderate corrosion and high temperatures. Renowned for their reliability, these pipes promise a long service life, impressive thermal stability, and strong resistance to oxidation. MERIH STAINLESS takes pride in ensuring that each pipe meets international standards, blending precision engineering with rigorous quality control. These pipes find extensive use in automotive, industrial, and construction sectors for efficient fluid and gas transport.
Stainless Steel 409 Pipes are made from ferritic stainless steel, featuring about 10–11.5% chromium, low carbon content (≤0.08%), and trace amounts of titanium, manganese, and silicon. This unique blend gives them excellent oxidation resistance and moderate corrosion protection in high-temperature settings. In terms of mechanical properties, 409 Pipes boast a tensile strength of around 450–550 MPa, a yield strength of 250–350 MPa, and good ductility for bending and shaping. Their ability to resist high-temperature oxidation makes them ideal for exhaust systems and industrial furnaces, while their moderate corrosion resistance ensures they hold up well in mildly corrosive environments.
