About SS 441
Dual-stabilised ferritic SS 441 (UNS S44100) stockist and exporter in Mumbai. Sheet, coil, plate and tube for exhaust manifolds, boilers and heat exchangers with 3.1 MTC.
SS 441 is an 18% chromium ferritic stainless steel dual-stabilised with titanium and niobium, giving significantly better high-temperature strength and oxidation resistance than 409 or 430. It is used for hot-end exhaust manifolds, heat exchangers, condensing boiler flues and appliance components where thermal fatigue resistance matters.
Steelco Metal & Alloys stocks SS 441 (UNS S44100) in Mumbai, India as a stockist, importer and exporter, and ships to 40+ countries. Every dispatch carries EN 10204 3.1 (3.2 on request) mill test certificates, PMI verification and is open to third-party inspection.
