As compared to the traditional austenitic stainless steel grade i.e. – 316, S31803 Stainless Steel Pipe is 10% lighter. This is because of the improved mechanical strength of the alloy. Since designers are able to use the alloy’s superior tensile strength properties and design lighter gauged products, the overall Duplex S31803 Pipe Price could be reduced. Hence S31803 Pipe Suppliers all across the world promote the use of this alloy in various industries. The ASTM A790/A928 CL1 UNS S31803 pipes find applications in many industries such as Chemical processing, Transport and Storage, Pollution control equipment, Pulp and paper manufacturing, Marine environments, Oil and gas refining ,Oil and gas exploration and offshore rigs as well as in Chemical process Plant.


The specification for standard ASTM SA 790 covers seamless as well as straight- seam welded duplex or ferritic -austenitic stainless steel pipes. This grade of pipes such as the ASME SA 790 S31803 is typically meant for use in general applications, where the alloy could be exposed to corrosive solution or compound containing environments. This SA 790 UNS S31803 specification particularly emphasises on the alloy’s resistance to SCC or stress related corrosion cracking. The ASTM A790 GRADE S31803 pipe must be produced by either the seamless or an automatic welding process. According to the ASTM A790 UNS S31803 Seamless specification , there must be no addition of filler metals in the welding operation. Heat analysis needs to be performed on the A790 S31803 SMLS on order to determine the percentages of the specified elements. Several tests must be performed on the ASTM A790 S31803 equivalent to conform to the requirements as specified in the standard. Tests such as hardening tests, tension tests, flattening tests, hydrostatic tests and non- destructive electric must be administered to the ASTM A790 UNS S31803 pipe.

The specification for ASTM A928 covers standard requirements for duplex grade stainless steel pipes. The term duplex has been used for the alloy of this Duplex S31803 Seamless Pipe because its microstructure consists of a roughly 50 : 50 proportion of both ferrite as well as austenite. The Welded A928 UNS S31803 specification covered in this grade is that the method used for welding is the electric fusion welded technique. Typically pipes welded with this specification technique such as the S31803 Welded Pipe require an addition of filler metals, which then makes the alloy well suited for use in corrosive service. After welding the Tubing S31803 heat treatment needs to be done in accordance to the specified temperature as well as the specified quench conditions.

Several grades of ferritic – austenitic or duplex steels like the Duplex S31803 tube have to conform to the requirements of both the applicable specification and grade designation for the UNS S31803 Pipe as well. Heat and product analyses on the Duplex UNS S31803 Pipe has to be conducted. Both of the fore mentioned analysis performed on the  UNS S31803 Pipe needs to conform to the requirements for that particular grade. The plate used in manufacturing the Duplex UNS S31803 Pipe has to conform to the required tensile strength properties. The stainless steel duplex grade UNS S31803 Pipe must also undergo several mechanical tests, similar to specification standard A790 UNS S31803. Similar to the SA 790 S31803 pipe, this ASTM A928 Duplex S31803 Seamless Pipe must be administered with tests such as transverse tension test, transverse guided- bend test, non- destructive test, hydrostatic test, as well as the non- destructive electric test.
