Datasheet

Avesta 2507 P100

Superduplex covered electrode designed for welding superduplex steel and equivalent steel grades such as EN 1.4410 / UNS S32570 and EN 1.4501 / UNS S32760. Avesta 2507/P100 is characterized by its exceptionally good arc stability and weld pool control. It is particularly well-suited for applications where impact toughness requirements are moderate, i.e. < 27 J at 0°C. For higher requirements, Avesta 2507/P100 rutile should be preferred. Excellent resistance to pitting, crevice and stress corrosion cracking in chloride containing environments. Meets the corrosion test requirements per ASTM G48 Methods A, B, E (40°C). Over-alloyed in nickel to promote austenite formation. Designed for welding in all positions. The operating temperature range is 0°C to 220°C.

Avesta 2507 P100 Rutil

Covered electrode designed for welding of superduplex steel and equivalent steel grades such as EN 1.4410 / UNS S32570 and EN 1.4501 / UNS S32760. Superduplex steels are particularly popular for desalination, pulp & paper, flue gas desulphurization and sea water systems. Developed to satisfy severe requirements, such as those in NORSOK M-601 and similar standards. Properties of the weld metal match those of the parent metal, offering high tensile strength and toughness as well as an excellent resistance to stress corrosion cracking and localized corrosion in chloride containing environments. Meets the corrosion test requirements for ASTM G48 Methods A, B and E (40°C) in both as-welded condition and after post-weld heat treatment (annealing at 1100 – 1150°C, followed by short air cooling and quenching). Over-alloyed in nickel to promote austenite formation. Designed for welding in all positions. The operating temperature range is –50°C to 220°C.
