The ASTM Sa789 specification covers conventional requirements for various stainless steel grades of nominal wall thickness, tubing for services which require general corrosion resistance, along with specific emphasis on resistance to SCC or stress related corrosion cracking. These stainless steels grades such as the Sa 789 UNS S32750 tend to be susceptible to embrittlement if used for a long and continuous periods at elevated temperatures, which would in turn cause loss of toughness and material tensile strength properties. Heat and product analyses on the Sa789 S32750 must be performed wherein that particular stainless steel grade needs to conform to the required chemical composition. For instance, the chemical composition of stainless steel grade UNS S32750 Tube must contain various alloying elements such as manganese, phosphorus, sulphur, silicon, nickel, chromium, molybdenum, carbon, nitrogen, copper, and others. The addition of these elements combined will contribute to the UNS S32750 Pipe alloy’s ability to resist various types of corrosion as well as its tensile strength.

All stainless steel S32750 Tubing needs to be furnished in a heat-treated condition, performed in accordance with the specified temperature as well as quench conditions. When the final heat treatment for alloy grade S32750 Super Duplex Pipe has been performed in a continuous furnace, or in instances when heat treated condition could be obtained directly by method of quenching after a hot forming process, the number of tubes of the same size as well as the same heat from the lot could be determined from the prearranged sizes of these tubes. The stainless steel Super Duplex 2507 UNS S32750 Pipe material has to conform to the prescribed tensile strength as well as the hardness properties as mentioned in the ASTM Sa789 specification . Typically S32750 Pipe Suppliers recommend administering several mechanical tests such as flange test (for welded tubes), tension test, flaring test (for seamless tubes), hardness test, and reverse flattening test to be performed on the stainless steel tubing. Each Saf 2507 UNS S32750 Pipe tube falling under the ASTM Sa789 specification must also be subjected to the non- destructive electric test or the hydrostatic test as well.

 

The ASTM Sa 790 specification covers several grade of ferritic/austenitic or duplex stainless steel seamless and straight-seam welded pipe. Generally, the pipes covered under specification Sa 790 UNS S32750 have been designed and are meant for general corrosive application, with emphasis specifically placed on resistance to SCC or stress related corrosion cracking. The S32750 Duplex Stainless Steel Pipe as per the specification must be manufactured by either a seamless or an automatic welding process. There is no addition of filler metal in the stainless steel grade Sa 790 S32750 alloys welding operation. Heat analysis shall be performed on the alloy A790 S32750  in order to determine the percentages of the elements specified. Tests such as the Tension tests, hydrostatic tests, hardening tests, flattening tests, and non- destructive electric tests must be administered on the alloy grade S32750 Duplex Stainless Steel Pipe ASTM Sa 790 specification. Further, as per the ASTM Sa 790 specification, this Saf 2507 UNS S32750 Pipe needs to also be produced in such a manner that it conforms to the requirements of the ASTM Sa 790 specification.
