We pride ourselves on delivering top-notch ferritic stainless steel solutions that cater to a variety of industrial and commercial needs. With a strong emphasis on durability, precision, and keeping our customers happy, Emilio Stainless produces SS 439 tubing that adheres to global performance and quality standards. Our tubes are designed to offer outstanding corrosion resistance, high-temperature strength, and excellent weldability. Thanks to our advanced manufacturing techniques and attentive service, Emilio Stainless has earned a solid reputation in the Philippine stainless steel market, providing tubing for both structural and functional applications.
Our Stainless Steel 439 tubing is crafted from a titanium-stabilized ferritic stainless steel alloy, featuring around 17–19% chromium and low carbon content. The addition of titanium boosts resistance to intergranular corrosion and enhances weldability. SS 439 boasts a tensile strength ranging from 430–590 MPa and a yield strength of about 275 MPa. Plus, it excels in oxidation resistance at high temperatures. These impressive mechanical and chemical properties make SS 439 tubing a fantastic choice for situations where strength, corrosion resistance, and cost-effectiveness are essential in mildly aggressive environments.
