Link to Active This link will always route to the current Active version of the standard. All tests results should comply with the given requirements. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. CIP offers two post-plating services: Electroplating Mechanical Galvanizing vs.
Nonmagnetic Coatings on Magnetic Basis Metals. Uniformity of thickness depends on part size aetm shape with typically thinner deposits on edges and thicker deposits in recesses.
Mechanical Plating – ASTM B Mechanical Galvanizing | Custom Industrial Processing
Electroplating The atsm advantage of mechanical plating over b659 is the elimination of hydrogen embrittlement. Specializing in Mechanical Zinc Plating and Galvanizing Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses.
We also work with both Type I as coated, without supplementary treatment and Type II with chromate conversion treatment B specifications for special processing needs.
Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
The main advantage b6695 mechanical plating over electroplating is the elimination of hydrogen embrittlement. Work Item s – proposed revisions of this astk. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. Custom Industrial Processing, Inc. Hot Dip Galvanizing Resin Impregnation.
All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. The thickest coating classes are usually referred to as “mechanically galvanized”. CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required.
Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e.
This abstract is a brief summary of the referenced standard. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement.

ASTM B – Portland Bolt
The inch-pound equivalents of SI units are given for informational purposes. Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels are highly susceptible. Historical Version s – view previous versions of standard.
This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. 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. What is Hydrogen Embrittlement Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat.
