We are professional A182-F60 Stainless Steel Forged Forging
Flanges(UNS S32205,AISI 318LN,SUS 329J3L) factory from china
NAS 329J3L (UNS S32205) 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.
Workability
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.
Weldability
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.
Heat Treatment
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.
Pickling
A mixture of nitric acid and fluoric acid is used in pickling.
However, because descaling is somewhat difficult in comparison with
Type 304, alkali immersion before acid pickling, and if possible,
shot blasting are extremely effective.
Applications
Chemical Plant, Chemical Tanker
Seawater desalination Plant, Seawater pump
Thermal power plant flue gas desulfurization plants
Pulp and paper plants
Bridge
