What is ASTM A789 Tubing?

The ASTM A789 Tubing material is a type of stainless steel that has good corrosion resisting properties, with a particular focus on resisting stress corrosion cracking. The tubes are manufactured in accordance to ASTM A789/ A1789M standards and they approximately contain 50% ferrite and 50% austenite. The ASTM A789 Tube is quite susceptible to embrittlement, and it should not be used for a prolonged period at elevated temperatures.

It is essential for the ASTM A789M Duplex Condenser Tube to undergo a product analysis, and a heat analysis procedure, as mandated by the specification. The A789 material has chromium, molybdenum and nitrogen in the alloy which enhance its resistance to pitting and crevice corrosion. The SA 789 Duplex Boiler Tubes can be found in applications like brackish water, bleaching operation, food processing industry, etc. They come with a min tensile and yield strengths of 655Mpa and 450Mpa respectively.

Heat Treatment Requirement for ASTM A789 Seamless Tubes

The heat treated condition is mandatory for all ASTM A789 Duplex Coil Tubing. There is an option to perform the final heat treatment in a continuous or batch-type furnace right after hot-forming. The temperature during the heat treatment must not fall below the specified minimum for solution treatment of.

The ASTM A789 Seamless Tubes can undergo individual water quenching or any other rapid cooling method. The heat treatment procedures help to alter the microstructure of the A789 material and the tubes can achieve desirable mechanical properties.
