Kunj Sheets and Plates is a trusted manufacturer and supplier of **Stainless Steel 439 Angles**, based in Chennai, India. We take pride in providing top-notch structural stainless steel products that cater to a variety of industrial needs. SS 439 is a ferritic stainless steel that’s stabilized with titanium, which enhances its resistance to corrosion, oxidation, and intergranular attack, particularly in welded situations. These angles are perfect for applications that demand high formability and corrosion resistance, even at elevated temperatures. At Kunj, we ensure that every stainless steel 439 angle is crafted with precision, rigorously quality-tested, and delivered promptly, serving a wide range of industries from construction and automotive to food processing and energy.
**Stainless Steel 439 Angles** consist of about 17–19% chromium, with titanium added for stabilization. This ferritic stainless steel is known for its excellent resistance to oxidation and corrosion, making it particularly suitable for exhaust systems and high-temperature settings. It boasts a tensile strength of around 450–600 MPa and a yield strength of about 250 MPa, along with good ductility and weldability. SS 439 also shows better resistance to stress corrosion cracking compared to many austenitic grades, maintaining its structural integrity even under thermal cycling. These characteristics make it a practical and cost-effective alternative to pricier stainless steels in environments with moderate corrosion.
