(Specification)Standard Specification for Borated Stainless Steel Plate, Sheet, and Strip for Nuclear Application
Standard Specification for Borated Stainless Steel Plate, Sheet, and Strip for Nuclear Application
ABSTRACT
This specification covers chromium-nickel stainless steel plate, sheet, and strip, modified by the addition of natural or enriched boron, for nuclear application. The austenitic chromium-nickel steels shall be solution annealed to meet the mechanical property requirements. The chemical analysis of representative material shall be performed to determine the required percentage of chemical elements. The tensile and hardness property requirements of the materials are presented. In the case of sheet or strip produced in coil form, two or more hardness test; one impact test, when required; and one or more tension test shall be made on specimens taken from each coil. In the case of sheet, strip, or plate produced in cut lengths, one tension test; one impact test, when required; and one or more hardness tests shall be made on each 100 or less pieces of the same heat and nominal thickness rolled separately or continuously and heat treated within the same operating period, either as a lot or continuously.
SCOPE
1.1 This specification covers chromium-nickel stainless steel plate, sheet, and strip, modified by the addition of natural or enriched boron, for nuclear application.
1.2 Borated stainless steels covered by this specification, because of their particular alloy content and specialized properties, may require special care in their fabrication and welding. Specific procedures are of fundamental importance, and it is presupposed that all parameters will be in accordance with approved methods capable of producing the desired properties in the finished fabrication.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
