This specification covers UNS N06333 alloy welded tubes intended for heat-resisting applications and general corrosive service. Each tube should be made from the flat-rolled alloy by an automatic welding process without any filler metal additions and subsequently furnished annealed with the oxide removed. Descaling is not necessary when the final heat treatment is performed in a protective atmosphere. A flattening test and a flange test will be performed on each end of one tube per lot.

1.1 This specification covers alloy UNS N06333 in the form of welded tube intended for heat-resisting applications and general corrosive service.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The following precautionary statement pertains only to the test methods portion, Section 13, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
