About ER347 / E347-16
ER347 wire and E347-16 niobium-stabilised electrodes for welding SS 321 and SS 347 up to 815 C. Mumbai stockist, importer and exporter to 40+ countries.
ER347 and E347-16 are stabilised with niobium, which ties up carbon so chromium carbides cannot form during high-temperature service. They are used to weld SS 321 and SS 347 in equipment running between 425 °C and 815 °C, such as refinery heaters and exhaust systems.
Steelco Metal & Alloys stocks ER347 / E347-16 (AWS A5.9 / A5.4) 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.
