What is ASTM a815?
The ASTM A815 covers Duplex Steel and Super Duplex Pipe Fittings /
Buttweld Fittings used for bleaching equipment in the pulp and
paper industry also for high-temperature service.
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.
S32750 duplex pipe fittings is one of the buttweld fittings and is
available in various shapes, sizes and specifications. This is used
in marine industries, nuclear projects, power plants and other
chemical industries. The durability of ASTM A815 WPS S32750
Fittings is excellent and the specification of this has two types
i.e. WP and CR. By using several chemicals like carbon, manganese,
phosphorus, silicon and many more are used. Several grades are also
involved like ASTM A815 UNS S31803, A815 UNS S32750 lot more. ASTM
A815 WPS 32750 Elbowpipe fittings is usually design to work as in
high strength, corrosion resistance to be high, perfect
weldability. All these features will be available in the product
manufactured by us. As earlier said that there are several types of
grades,A815 UNS S32750 Duplex Tube fittings is one of them.

What is the difference between UNS s32750 and s32760?
S32760 Super Duplex Stainless Steel
While involving extended exposure to temperatures more than 572F
use of S32760 is not recommended. The chemical composition of
S32750 and S32760 are similar; however, the latter contains
slightly more copper and tungsten. The copper content (min.
