Stainless Steel 441 Flats engineered for exceptional oxidation resistance, high-temperature strength, and excellent weldability. As a leading supplier in Chennai, we offer SS 441 flats (UNS S44100 / EN 1.4509), a dual-stabilized (niobium + titanium) ferritic grade that outperforms traditional 409 and 439 in demanding exhaust and thermal applications while providing a cost-effective alternative to austenitic grades like 304.
Grade 441 is a dual-stabilized ferritic stainless steel, specifically developed to provide superior high-temperature strength and creep resistance. The defining characteristic of 441 flats is the dual addition of Titanium (Ti) and Niobium (Nb). This combination ensures the material maintains its structural integrity and remains resistant to intergranular corrosion, even in the heat-affected zones of complex welds. These flats are ideal for industries requiring reliable materials for both structural and high-temperature applications.
