Khush Sheets and Plates is a reputable manufacturer and supplier of Stainless Steel 439 Angles, located in Delhi, India. SS 439 is a titanium-stabilized ferritic stainless steel known for its outstanding resistance to corrosion, oxidation, and stress corrosion cracking, especially in high-temperature and automotive settings. Our 439 stainless steel angles are produced in line with ASTM A240 and A276 standards, ensuring top-notch weldability, formability, and precise dimensions. Khush Sheets and Plates provides high-quality SS 439 structural angles suitable for various industries, including automotive exhaust systems, heat exchangers, construction, and fabrication, delivering durability and cost-effectiveness for demanding applications.
Stainless Steel 439 is a titanium-stabilized ferritic alloy that contains about 17–19% chromium and very little nickel, with titanium added to enhance grain structure stability. This unique composition boosts resistance to intergranular corrosion and oxidation. It boasts a tensile strength of around 450–530 MPa, a yield strength of about 230 MPa, and an elongation of 25% or more. Unlike austenitic grades, SS 439 has low thermal expansion and better thermal conductivity, making it perfect for high-temperature applications. Khush Sheets and Plates guarantees that all 439 angles are meticulously fabricated and tested for corrosion resistance, mechanical performance, and surface finish.
