This specification covers hot- and cold-rolled zirconium and zirconium alloy sheet, strip, and plate. One unalloyed and three alloys for use in nuclear applications are described. Materials covered by this specification shall be produced by multiple vacuum melting in arc furnaces, electron beam melting, or other melting processes. The material shall conform to the required chemical composition for tin, iron, chromium, nickel, niobium, and oxygen. The alloy shall also conform to the specified maximum impurity values for aluminum, boron, cadmium, calcium, carbon, chromium, cobalt, copper, hafnium, hydrogen, iron, magnesium, manganese, molybdenum, nickel, niobium, nitrogen, phosphorus, silicon, tin, tungsten, titanium, and uranium. The material shall conform to the prescribed mechanical properties such as tensile strength, yield strength, and elongation. Two samples chosen at random shall be corrosion tested. Sheet, strip, or plate shall conform to the permissible variations in the dimensions prescribed. The material shall also undergo tests which shall include ultrasonic inspection and other special tests.

1.1 This specification covers hot- and cold-rolled zirconium and zirconium alloy sheet, strip, and plate.

1.2 One unalloyed and three alloys for use in nuclear applications are described.

1.3 The products covered in this specification include the following forms and sizes:

1.3.1 Sheet, 24 in. [600 mm] or more in width; under 0.187 in. [4.8 mm) in thickness,

1.3.2 Strip, less than 24 in. [600 mm] in width; under 0.187 in. [4.8 mm] in thickness, and

1.3.3 Plate, over 10 in. [250 mm] in width; 0.187 in. [4.8 mm] and over in thickness.

Note 1—Material over 0.187 in. [4.8 mm] in thickness and less than 10 in. [250 mm] wide is covered as bar in Specification B351/B351M.

1.4 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.

1.5 The following precautionary caveat pertains only to the test method portions 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.
