ASTM A789 Duplex S32520 Stainless Steel Tube for Heat Exchanger and Petroleum Industry
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.
The grade S32520 is a Super Duplex stainless steel. It is designed to provide the highest level of corrosion resistance and strength among the standard duplex families.
