Astm A928 uns S31803 super duplex stainless steel pipe
We are one of the biggest manufactures of stainless steel & duplex
steel & alloy steel tubes and pipes in China. With development more
than 20 years, we have accumulated a great many clients all around
the world and Yuhong products also won the great praise among the
customers.
Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.
Duplex stainless steels are in most cases, tougher than ferritic
stainless steels. Strengths of duplex stainless steels can in some
cases be double that for austenitic stainless steels. The duplex
stainless steels are considered resistant to stress corrosion
cracking, they are not as resistant to this form of attack as
ferritic stainless steels. However, the corrosion resistance of the
least resistant duplex stainless steels is greater than that for
the most commonly used grades of stainless steels, i.e. 304 and
316.
Duplex stainless steels are also magnetic, a property that can be
used to easily differentiate them from common austenitic grades of
stainless.
Property data given in this document is typical for flat rolled
products covered by ASTM A240/A240M. ASTM, EN or other standards
may cover products sold. It is reasonable to expect specifications
in these standards to be similar but not necessarily identical to
those given in this datasheet.
