ASTM B177-93 PDF

1.1 This guide 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 usually thicker than decorative deposits.

1.2 This guide 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 base metals. Specified chromium electrodeposits on ferrous surfaces are defined in Specification B 650.

1.3 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.
