ASTM B523/B523M-12a

Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Tubes

ABSTRACT
This specification covers the three grades of zirconium and zirconium alloy seamless and welded tubes. The tubes are furnished in three grades as Grade R60702 which is an unalloyed zirconium, Grade R60704 which is zirconium-tin alloy, and Grade R60705 which is zirconium-niobium alloy. Seamless tube shall be made by any seamless method. Welded tube shall be made from sheet or strip by an automatic arc-welding process or other method of welding. Filler metal shall not be used. The material shall conform to the required chemical compostion for zirconium, hafnium, iron, chromium, tin, hydrogen, nitrogen, carbon, niobium, and oxygen. The materials shall conform to the required tensile properties such as tensile strength, yield strength, and elongation.
SCOPE
1.1 This specification2 covers two grades of zirconium and zirconium alloy seamless and welded tubes.  
1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. SI values cannot be mixed with inch-pound values.  
1.3 The following precautionary caveat pertains only to the test methods portion of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
