1. Scope 1.1 This standard provides information about the deposition of chromium on steel for engineering uses. This is sometimes called "functional" or "hard" chromium and is usually applied directly to the basis metal and is much thicker than decorative deposits. 1.2 This specification is not intended as a standardized procedure, but as a guide for obtaining smooth, adherent coatings of chromium of a desired thickness while retaining the required physical and mechanical properties of the steel base. Requirements for chromium electrodeposits on ferrous surfaces are defined in Specification B650. 1.3 This standard does not purport to address all of the safety problems, 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.
