NT-2553
AWS Specification: ER-2553
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS:

For welding super duplex stainless steel grades chemical composition approx. 24-27% Cr, 6-9% Ni, 3-4% Mo, 0.10-0.25% N alloyed also with Cu and/or W

II. DESCRIPTION:

NT-2553 is highly suitable for welding ferritic-austenitic superduplex steels. By virtue of specific alloy composition the deposit has, in addition to high tensile strength and toughness, also excellent resistance to stress corrosion cracking and pitting corrosion. The operating temperature is -50 °C up to +250 °C. Well suited for the conditions in the offshore field.
