Liam Pipes and Tubes is your go-to manufacturer and supplier of Stainless Steel 439 Pipes right here in Houston, USA. We pride ourselves on delivering cost-effective and high-performance piping solutions. Stainless Steel 439 is a ferritic stainless steel that stands out for its impressive corrosion resistance, especially in oxidizing environments, and it boasts better weldability than many other alloys in the 400 series. At Liam Pipes and Tubes, we ensure our 439 pipes are precisely crafted to meet global quality standards, serving industries like automotive, construction, and heat exchangers. Our dedication to durability, prompt delivery, and customer satisfaction has made us a trusted name in stainless steel piping solutions.
When it comes to composition, Stainless Steel 439 Pipes primarily consist of Chromium (17.0–19.0%), with minimal Carbon (≤0.03%) and a touch of Titanium to enhance weldability and prevent grain boundary corrosion. These pipes have a tensile strength ranging from about 415 to 600 MPa and a yield strength of around 240 MPa, with elongation between 25% and 30%. Thanks to its mechanical properties and thermal stability, Stainless Steel 439 is perfect for applications that face moderate corrosion and high temperatures.
