- Scope
1.1 This specification covers two wrought iron-cobalt alloy types for use in magnetic components requiring high permeability at and above 15 kG (1.5 T) or high magnetic saturation. The specific alloy types covered are:
Alloy Type
UNS
Nominal Composition
1
R30005
498201;% Co, 498201;% Fe, 28201;% V
2
K92650
278201;% Co, 0.508201;% Cr, balance Fe
1.1.1 This specification also covers material supplied by a producer in the form and physical condition suitable for fabrication into parts that will later be given final heat treatment to achieve the desired magnetic characteristics and, where required, mechanical properties. It covers material supplied in form of forging billets, hot-rolled products (that is, bar, plate, and strip), cold-finished bars, and cold-rolled strip.
1.2 This specification does not cover parts produced by casting or by powder metallurgical techniques.
1.3 The values stated in customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
1.4 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.
