We, Duplex Steel & Alloys are a globally acclaimed
producer and supplier of Stainless
Steel 347/347H Flanges. Our organization has advanced
equipment that is run by competent personnel, allowing us to ensure the
quality of our goods, including flanges. We only use good quality raw
materials to create these flanges.
Stainless Steel 347 Flanges and SS 321 have numerous
similarities, in terms of properties. Due to the addition of columbium, it
is frequently used as a common substitution and stable alternative to SS
304. Columbium's presence also helps the alloy to have the best capacity to
resist intergranular corrosion caused by using these flanges at elevated
temperature ranges. The alloy also has superior creep resistance and stress
rupture corrosion resistance. It can even endure temperatures as high as
1650. SS 347 alloy products are frequently used in high-temperature
applications like rocket engines and chemical manufacturing.

Clients often utilize
Stainless Steel 347 Flanges where environmental stability is a major
consideration. Various welding processes can be used to deal with the alloy. Because of
its capacity to endure high temperatures, it must be heated between 2100°F and 2250°F.
Cold reduction is the only method that can reduce the thickness, increase its yield
strength, can take advantage of the alloy's exceptional properties.
Stainless Steel 347H Flanges are an altered version
of SS 347 with higher carbon content. The alloy comprises columbium and varying amounts
of tantalum, which alters SS 347. These added elements allow the alloy to endure higher
temperatures and prevent corrosion. It is utilized in high-stress, corrosive settings.
High-temperature manufacturing, steam pipes, chemical operations, and steam maintenance
are some of their applications that utilize SS 347H flanges.
Duplex Steel & Alloys produces these flanges in various types
and sizes as needed by the client and their applications. We provide these high-quality
flanges at affordable costs.
