Vinit Stainless is one of the top manufacturers and suppliers of stainless steel products from Chennai, India. With a commitment to excellence, we have been able to provide a wide variety of stainless steel products, such as Stainless Steel 439 Pipes. Our products include durable corrosion-free and excellent-performance industrial applications in many. However, Vinit Stainless primarily focuses on a high level of customer satisfaction due to its consideration of prompt delivery and competitive quotation for various purposes in the country.
Stainless Steel 439 is a ferritic grade composed primarily of chromium (17-19%) and other trace elements such as silicon, manganese, carbon etc. This alloy provides excellent resistance to oxidation and corrosion, especially in high temperature environments. The composition also contains trace amounts of molybdenum and nitrogen to enhance its strength and durability. The mechanical properties of stainless steel 439 pipe include excellent tensile strength (up to 450 MPa), yield strength (up to 275 MPa), and approximately 20% higher length, making it suitable for automotive applications and technical applications
