C&N finished a duplex material project for Thailand clients, the material include UNS S31803 paltes,
A182 F51 flange and duplex Seamless & Welded Tube, as the end user have very strict requirements on
the supplier capacity, we arrange the raw material from BAOSTEEL. finally these duplex material get
clients hightly remark.

With years corportation with BAOSTEEL, TISCO ETC. We can get competitive offer and quick delivery.
right now we holds stock of Super Duplex stainless steel plate specifications UNS S32750 (1.4410) and
UNS S32760 (1.4501).UNS S31803 - UNS S32205.

Duplex stainless steel was developed as a product which could improve upon some of the technical weaknesses of the standard austenitic and ferritic stainless steels that are available in the market. Both have low strength, ferritic steels have poor low temperature toughness, and austenitic steels have a very low resistance to stress corrosion cracking. Duplex stainless has a microstructure which is split roughly 50:50 between austenite and ferrite and balancing of these phases provides the following benefits:

Higher strength which is around twice that of Type 304 austenitic stainless steel. This leads to reduced plate thicknesses being used in fabrications reducing the weight which is of particular significance in items such as pressure vessels, storage tanks, and structural applications such as bridges.
Good weldability in thick plates.
Good low temperature toughness.
Resistance to stress corrosion cracking of importance in many applications including hot water tanks, process plant, brewing tanks, and desalination plant.
