UNS S32750 tube

What is ASTM A790 UNS S32750?

The SA 790 UNS S32750 Material is a super duplex stainless steel that has 25% chromium, 7% nickel and 4% molybdenum in its alloy. The composition helps to make the pipes strong and corrosion resistant. Thus, the SA 789 UNS S32750 Heater Tubes can be used in acidic environments with high corrosion levels. The material possesses high strength and can be used in high pressure applications. They are used in industries like pulp & paper, water desalination, chemical, etc.

What is SA 789 UNS S32750?

The super duplex UNS S32750 Pipe material is generally cold drawn and can be hardened by cold working. They have easy weldability and the material produces less carbide precipitation which helps to avoid inter granular corrosion. SA789 S32750 Bright Annealed Tubes are used in applications below 600 °F and they have high min yield strength of 57Mpa.
