4.Corrosion resistance
926 austenitic stainless steel with nitrogen content 0.2%, the molybdenum content 6.5%, the remaining of a large number of
the two elements prevents from the pitting corrosion in halide media and crevice corrosion .At the same time, not only
ensures the stability of metallographic, nickel and nitrogen also reduce the trend of intergranular segregation.
Alloy 926 has good resistance to local corrosion in the chloride ion media and special corrosion resistance for the 25% nickel content .
Also has good corrosion resistance in high temperature and high concentration sulfuric acid, phosphoric acid, acid gas, water, salt
and organic matter such as environment .
5.Structure
Face-centered cubic lattice structure.
6.Applications
(1). The fire control system, water purification system, Marine engineering, hydraulic pipe perfusion system.
(2). In the acidic gas piping, joints, air system.
(3) in the production of phosphate evaporator, heat exchanger, filter, mixer, etc.
(4).In the use of sewage cooling condensation and pipeline system in power plant.
(5).Use organic jiggled, agents of production of acid chloride derivatives.
(6). White agent production of cellulose pulp.
(7). Marine engineering.
(8). Flue gas desulfurization system components.
(9). Sulfuric acid condensation and separation system.
(10). The transportation of corrosive chemical container.
(11). Reverse osmosis desalination plant.
