What is duplex and super duplex S32750/2507 Flanges ?
Duplex and super duplex S32750 flanges are commonly known as the mixture of both ferritic and austenitic alloys. These flanges are highly ductile and durable. These flanges are commonly used for marine application, and aircraft making. Duplex and super duplex s32750 flanges have high content of molybdenum. The inclusion of molybdenum in the grade is the basic difference between super duplex and duplex grade.
Molybdenum is a strong ductile grade. It has various properties and characteristics which provides excellent strength and robustness to the grade. The molybdenum grade also has natural resistance from various chemical and physical reactions.
Duplex and super duplex S32750 flanges are made of a great mixture of molybdenum, chromium and other ductile elements. These elements are amazingly durable and it has excellent welding and pitting capacity. The tensile and yield strength of these flanges is extremely high. The melting point of these flanges is also very high, approximately 1350°. The grade provides excellent resistance from corrosion, crevice corrosion and stress cracking. The minimum tensile strength of this alloy is 75000 psi and the yield strength is 30000 Psi.
