ASTM B516-03 pdf free.Standard Specification for Welded Nickel-Chromium-Iron Alloy (UNS N06600, UNS N06603, UNS N06025, and UNS N06045) Tubes.
This specification covers welded UNS N06600*,NO6603，N06025，and NO6045 alloy boiler， heat exchanger,and condenser tubes for general corrosion resisting and low orhigh temperature service.This specification covers tubes 1/s to 5 in.(3.18 to 127
mm), inclusive, in outside diameter and 0.015 to 0.500 in.(0.38to 12.70 mm), inclusive, in wall thickness.Table 2 of Speci fication B 751 lists the dimensional requirements of these sizes.Tubes having other dimensions may be furnished providedsuch tubing complies with all other requirements of thisspecification.The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.This standard does not purport to address all of thesafety concerns，if any,associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet for this product/material as provided by the manufacturer; to establish appropriate safety andhealth practices, and determine the applicability of regulatorylimitations prior to use.B 751 Specification for General Requirements for Nickeland Nickel Alloy Welded Tube2.B899 Terminology Relating to Non-ferrous Metals andAlloys2
Terms defined in Terminology B 899 shall apply unlessdefined otherwise in this standard.
Tube shall be made from flat-rolled alloy by an auto-matic welding process with no addition or filler metal.Subse-quent to welding and prior to final annealing, the material shallbe cold-worked in either the weld metal only or both weld andbase metal.Tube shall be furnished with oxide removed. Whenbright annealing is used, descaling is not necessary.
The material shall conform to the composition limitsspecified in Table 1.One test is required for each lot as definedin Specification B 751.
If a product analysis is performed,it shall meet thechemistry limits prescribed in Table 1, subject to the analysistolerances specified in Specification B 751.
Mechanical Properties and Other Requirements:Mechanical Properties—-The material shall conform tothe mechanical property requirements specified in Table 2.Onetest is required for each lot as defined in Specification R 751.ASTM B516 pdf download.
