Duplex S31803 Flanges

What is Duplex S31803 Flanges

Duplex and super duplex flanges are the most demanded grades in the steel industry today. These Duplex S31803 Flanges are made of high alloyed metals and raw material. This grade is enriched with excellent properties and characteristics.

Duplex S31803 flanges are made from an excellent combination of elements. The mixture of these elements includes a high amount of chromium content that increases the durability and strength of the grades. It also includes other elements like molybdenum, nickel, nitrogen, etc.

The combination includes at least 20-28% of chromium content, it also includes nickel up-to 9% and at least 5% of molybdenum content. This combination provides extreme stability and efficiency to this grade.

Duplex S31803 flanges are made of a mixture of austenitic and ferritic metals. These flanges are commonly used in boilers as they have high melting and boiling points. Duplex S31803 flanges are not recommended for use above 300°C. The grade provides high resistance from oxidation above 50°C. It also protects from corrosion, crevice corrosion and stress cracking. Duplex S31803 flanges also have low carbon content which reduces the chances of carbide precipitation. These flanges are obtainable in various sizes, shapes and thicknesses.
