S32001 3 Inch Stainless Steel Pipe ASTM A789 Standard Shot Blasting Finished
Stainless Steel Tubing ASTM A789 S32001 Pipe
UNS S32001 is a stainless steel with a mixed ferrite and austenite structure. UNS S32001 provides high yield strength (65 ksi minimum (448 MPa)), drawing and welding characteristics are good, excellent chloride stress corrosion cracking resistance, and high cyclic oxidation resistance up to 1800°F (982°C). It exhibits high ductility (super plasticity) at high temperatures (1800°F (982°C)). Compared to similar duplex alloys such as 2205, Alloy 19D SS is more economical but less corrosion resistant due to the lower alloy content (particularly molybdenum).
Standards:
ASTM A789 Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service
Application:
Chemical processing, transport and storage,
Oil and Gas exploration and processing equipment,
Marine and other high chloride environments,
Pulp and paper digesters, liquor tanks and paper machines.
