Raw Material Selection
The manufacturing process of buttweld fittings begins with the careful selection of raw materials.
Duplex Steel UNS S31803 Buttweld Fittings are widely recognized for their outstanding mechanical properties, offering a perfect combination of high strength and excellent resistance to corrosion. Duplex Steel UNS S31803, also known as 1.4462, combines the advantages of stainless steels that are ferritic and austenitic, which makes it perfect for uses requiring enhanced durability in challenging environments. These fittings are commonly used in industries like chemical processing, oil and gas, and marine applications due to their resistance to chloride stress, corrosion and pitting.
