What is SUS439 2D Stainless Steel Coil Strip?

SUS439 2D Stainless Steel Coil Strip refers to a titanium-stabilized, ferritic stainless steel (Grade 439) supplied in a coil form with a dull, matte surface finish (2D), offering good corrosion resistance, excellent weldability, and formability for automotive exhaust, appliances, and heat exchangers, making it a versatile choice for high-temperature, chloride-prone applications.

GNEE Steel offers SUS439 2D stainless steel coils/strips conforming to ASTM A240 / JIS G4305 standards, with a thickness range of 0.3–3.0 mm and widths up to 1500 mm. The product is made from a low-carbon ferritic stainless steel stabilized with 17–19% Cr and Ti, exhibiting excellent resistance to intergranular corrosion, pitting corrosion, and stress corrosion cracking, while maintaining good formability and weldability.
Furthermore, GNEE supports thickness tolerance control of ±0.05–0.1 mm and provides EN 10204 3.1 material certificates and third-party spectroscopic testing reports, making it suitable for demanding applications such as automotive exhaust systems, architectural decoration, home appliances, and food processing equipment.
