JACKSUN NOVA 2553

AWS A5.4: E2553-16

JACKSUN NOVA 2553 is a rutile-coated duplex stainless steel electrode, classified under AWS A5.4 E2553-16 and EN ISO 3581-A E 25 9 3 N L R 26.
Designed for welding duplex stainless steels (UNS S31803 / S32205) and similar grades.
Weld metal contains a balanced microstructure of austenite + ferrite, giving high strength with excellent corrosion resistance.
Excellent resistance to stress corrosion cracking, pitting, and crevice corrosion in chloride environments.
Weld deposits exhibit higher tensile and yield strength compared to standard austenitic stainless steels.
Ideal for chemical, oil & gas, desalination, and marine applications.(As per AWS A5.4 E2553-16 / EN ISO 3581-A E 25 9 3 N L R 26)
