AISI 441 EN 1.4509 Ferritic Stainless Steel Sheet Ti Nb Stabilized 2mm 1219x2438mm

AISI 441 EN 1.4509 Ferritic Stainless Steel Sheet

AISI 441 (EN 1.4509) is a titanium and niobium dual-stabilized ferritic stainless steel sheet developed for high-temperature and corrosion-resistant applications. The dual stabilization prevents sensitization, delivering excellent weldability, high-temperature oxidation resistance and thermal fatigue resistance. It is widely used in automotive exhaust systems, catalytic converters, heat exchangers and other heat-end components.

Product Highlights

• Ti+Nb Dual Stabilized: Prevents sensitization and improves weld zone toughness.
• High-Temperature Oxidation Resistance: Retains scale resistance in exhaust and heat-end service.
• Excellent Weldability: Suitable for tubes, manifolds and welded assemblies.
• Thermal Fatigue Resistance: Handles repeated thermal cycling in hot exhaust gas.
• Precision Thickness: Cold rolled 0.3–3.0mm with tolerance ±0.02mm.
• Cut-to-Size Service: 1000x2000mm, 1219x2438mm, 1500x3000mm and custom sizes.
