Leghe resistenti alla corrosione

1.4462, SUS 329J3L, UNS S31803 / S32205 - Duplex Stainless Steel

SUS 329J3L, UNS S32205, S31803 is an Austenitic-ferritic stainless steel, which has superior corrosion resistance and high strength. It has better localized corrosion resistance than Type 316L and 317L, and the steel is applied in the industrial fields like chemical plant, seawater desalination plant, seawater pump, and so on. We supplies this product in plate, sheet and strip form.

lavorabilità

High temperature strength is similar to Type 430 in the range of 1150~950℃. However the steel shows rapid increase in the strength below 900℃. Regarding cold workability, care is required as proof stress is high and elongation is low in comparison with Type 304.

saldabilità

Various welding methods are applicable in the same manner as with the standard austenitic stainless steels, including shielded metal arc welding, TIG welding, and plasma welding. Same duplex grade type welding consumable should be used.

Trattamento termico

Solution heat treatment should be performed in the range of 1020~1100℃ followed by rapid cooling. Cooling rate should be high in order to shorten the time exposing at temperature range which may cause the brittleness by 475℃ brittlement and σ phase formation.

decapaggio

Nel decapaggio viene utilizzata una miscela di acido nitrico e acido fluorico. Tuttavia, poiché la decalcificazione è alquanto difficile rispetto al tipo 304, l'immersione con alcali prima del decapaggio con acido e, se possibile, la granigliatura sono estremamente efficaci.
