ASTM A789 Duplex S32950 Stainless Steel Tube For Chemical and Petrochemical Processing
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.
Super Duplex UNS S32950 Seamless Pipes provide excellent impact strength and thermal conductivity, a low coefficient of thermal expansion, and excellent resistance to chloride stress corrosion. Super Duplex UNS S32950 Tubes offers superior localized corrosion resistance, and thus is appropriate to be used in chemical plants, water desalination plants, and similar severe environments.
