ASTM A789 tube

ASTM A789 tube

The American Society for Testing and Materials, ASTM A789/A789M can be described as standard specification for welded and seamless ferritic/austenitic stainless steel piping and tubing for general purpose uses. The duplex tubing and piping solutions produced under ASTM A789 tube specification helps to withstand corrosion cracking due to stress. The ASTM A789M welded pipe might also be used in applications that are prone to general corrosion. However, they should not be used for services that put the pipe in elevated temperature conditions for a prolonged time. Or else, the astm a789m Seamless and Welded Ferritic/Austenitic Stainless Steel can become brittle and result in eventual failure.
