ASTM A789 UNS S31803 seamless tube
What are the different types of surface finishes available for ASME SA 789 UNS S31803 seamless tube?
Annealed and Pickled finish involves a heat treatment process known as annealing, followed by pickling to remove oxide scales from the tube. Manufacturers give the tubes a bright-annealed finish by subjecting the tube to a controlled atmosphere annealing process followed by pickling.
Mechanical polishing involves the use of abrasive materials and tools to remove surface imperfections of the ASTM A789 UNS S31803 seamless tube. Manufacturers employ the electropolishing process to remove surface irregularities and contaminants and give the tubes a smooth, bright finish
