Looking for modern, high-performance Stainless Steel 441 Flanges that combine excellent corrosion resistance, superior weldability, and outstanding high-temperature stability at an economical price? Salem Stainless Steel Suppliers Pvt. Ltd., Chennai’s trusted stockist and supplier, offers top-quality SS 441 Flanges—a stabilized ferritic stainless steel grade designed as a superior alternative to 409 and 430 grades.
Grade 441 is a dual-stabilized ferritic stainless steel containing both Niobium and Titanium. The engineering superiority of 441 Flanges lies in its stabilization. While standard ferritic steels use only one stabilizing element, Grade 441 utilizes both Titanium (Ti) and Niobium (Nb). This combination ensures high-temperature strength and exceptional resistance to intergranular corrosion in the heat-affected zones of welded joints.
