ASTM A789 S32304 Stainless Steel Tube For Power Generation
Specifications
ASTM A789/ ASME SA789 steel pipe covers seamless and welded ferritic / austenitic stainless steel tubing for general services. The standard is also applied to duplex stainless steel tube material. All tubes in this standard shall be furnished with heat-treated conditions according to specified temperature and quench conditions. When the final heat treatment is in a continuous furnace, or when heat-treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat lot shall be determined from the prescribed sizes of the tubes.
ASTM A789 / ASME SA 789 Alloy 2304 UNS S32304 is a 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. The Alloy 2304 has corrosion resistance properties similar to 316L. Furthermore, its mechanical properties, i.e., yield strength, are twice those of 304L/316L austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications.
