Product Details

We are professional UNS S31803(1.4462,SAF 2205)Duplex Stainless Steel Plates Sheets Strips Coils factory from china
 
We could produce  SAF 2205 plate and sheets with Sizes range from 4.5MM thick to 200MM thickness, up to 3000 wide.
 
The thickness of SAF 2205 strips and coil that we could do range from 0.05MM to 3MM
 
The surface finish of SAF 2205 strips and coils that we could do is as follows:2B / 2D / BA
 
The hardness of EN SAF 2205 strip and coils that we could do is as follows:1/4 Hard, 1/2 Hard, 3/4 Hard, Full Hard, Spring Hard, Annealed, Pickled Soft
 
Customers can select a number of processing options to produce SAF 2205 plate to their exact specifications, reducing materiel costs, production time, scrap and internal handling. All stainless steel grades of plate can be cut
 
We can polish nearly any SAF 2205 plates,sheets,coils,strips to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Our SAF 2205 plate,sheets,coils,strips can be polished on one side or two sides.
 
In order to control the quality of SAF 2205 plate,sheets,coils,strips,Test pieces are cut from each plate,sheets,coils,strips and sent to our Metallurgical Laboratory, where, aided by a computerized Certificate of Test system, experts determine if the plate,sheets,coils,strips meet all requirements for shipment. Each plate,sheets,coils,strips is analyzed on an optical emission spectrometer to verify chemical content. The microstructure of the plate,sheets,coils,strips is examined for strength, ductility, and corrosion resistance. All additional scrap is separated by grade and returned to a melt shop for recycling
 

2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.
