what is ASTM A790 UNS S31803?
The ASTM A790 UNS S31803 is a high alloy duplex stainless steel grade. A790 UNS S31803 Pipe is designed with a dual-microstructure of austenitic and ferritic. These pipes are produced with a chemical content of chromium, nickel, and molybdenum with other constituting alloys. The ASTM A790 UNS S31803 Pipe is a nitrogen enhanced grade and are designed to combat corrosion problems that are common in the 300 series. The grade of pipes are very common in the duplex stainless steel family.
what is UNS S31803 Pipe?
The UNS S31803 pipe covers a standard specification of duplex steel material. The UNS S31803 Pipe is formed based on its crystalline structure and has excellent resistance to pitting and crevice corrosion-induced in marine systems. A Duplex UNS S31803 Pipe also resists sulfide stress corrosion in chloride-induced environments. These pipes have excellent strength and showcase good weldability and workability. The S31803 Steel Pipe has a minimum tensile strength of 621mpa with a minimum yield strength of 448mpa and can be elongated by 25%. These pipes have a Brinell hardness of 293 max and are generally manufactured in seamless and welded specifications. The Duplex S31803 Seamless Pipe is produced via an extrusion process as hot steel billets are passed through metal to correctly shape them. These pipes have excellent strength and excellent surface ovality and roundness.
A UNS S31803 Seamless Tube is less prone to corrosion and have a rough surface due to the extrusion process. These tubes are well suited for higher pressure and temperature applications. They have 20% higher strength and load-bearing capacity than an S31803 Welded Pipe. The welded pipe though offers a cost-effective alternative, but have no size restrictions and can be manufactured in long continuous lengths. The procurement of pipes of seamless grade is considerably low. The Duplex S31803 Pipe is commonly used in chemical process equipment, food processing, heat exchangers, oil field piping, flue gas desulfurization systems, etc. The S31803 Pipe Suppliers in India can transport these pipes easily due to the strategic position of the country.
