Emilio Stainless is a reputable manufacturer and supplier located in Manila, Philippines, with a focus on high-quality stainless steel 409 pipes. These pipes are celebrated for their durability, resistance to corrosion, and affordability. Crafted with precision and under strict quality control, they adhere to international standards and excel in applications that demand resistance to oxidation and moderate corrosion. Emilio Stainless takes pride in ensuring that each stainless steel 409 pipe boasts excellent weldability and formability, making them perfect for various industries, including automotive, exhaust systems, construction, and industrial processing, both in the Philippines and beyond.
Stainless steel 409 pipes are composed of a ferritic stainless steel alloy that contains around 10.5–11.7% chromium, up to 1% nickel, manganese, and a low carbon content typically below 0.08%. The addition of titanium stabilizes the alloy, preventing intergranular corrosion during the welding process. This unique composition offers good oxidation resistance up to approximately 675°C, moderate corrosion resistance, and outstanding thermal conductivity. The pipes generally exhibit tensile strength ranging from 380–450 MPa, making them suitable for structural and high-temperature applications.
