ASTM A790 UNS S32205 Pipe Manufacturing Process
Duplex steel UNS S32205 EFW pipe can be annealed between 1020 - 1100 degrees Celsius, with rapid cooling in air or water. If the ambient temperature rises above 300 degrees Celsius, the microstructure of the UNS S32205 material becomes brittle and precipitates. And if the temperature is below -50 degrees Celsius, the material undergoes a ductile to brittle transition. UNS S32205 duplex stainless steel pipe has a tensile strength of 655 MPa and a yield strength of 450 MPa. S32205 stainless steel pipe is widely used in wine tanks, pulp and paper digesters, and high-chlorine, marine environments.
ASTM A790 Standard Requirements
Piping products in the ASTM A790 standard must meet various specified requirements, including dimensions, appearance, chemical composition, mechanical properties, and more. According to the standard, these products must be processed by heat treatment, cold drawing, welding, machining, laser cutting, and other processes in order to obtain piping system components that meet the requirements. When purchasing ASTM A790 UNS S32205 pipe, it is important to ensure that the material meets the specified requirements of the ASTM A790 standard and is properly tested and certified. Our company HT PIPE is a reputable 2205 stainless steel supplier, manufacturer, or distributor who can provide the necessary information and ensure the quality and compliance of the pipe.
