4.Characteristics
(1)Corrosion resistance：good resistance to pitting and crevice corrosion in the chloride and containing amino acid environment,
good resistance to stress corrosion cracking in sodium chloride environment.
(2)With the contents of low-carbon and high-Nitrogen, can lessen the carbide and the precipitation of the second phase in the welding.
(3)High strength and toughness and impact strength for the visible part of nitrogen added in the alloy.
5.Applications
1.Flue gas desulfurization spray tower,
2.Reverse osmosis seawater desalination equipment and pump.
3.Chemical reaction kettle and pipeline.
4.heat exchanger using seawater media.
5.A crude oil distillation tower and metal filler.
6.Marine oil and gas equipment.
7.Scrubber drum, roller, tank, pipe, etc in the system of he pulp bleaching.
