Work Item s – proposed revisions of this standard. 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.
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. 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.
ASTM B – 04 Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel
Hot Dip Galvanizing Resin Impregnation. Electroplating Mechanical Galvanizing vs. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.
ASTM does not give any warranty express or implied or asgm any representation that the contents of this abstract are accurate, complete or up to date. Click here for a quote or call us at Electroplating The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.
This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.
It is the responsibility of the user b6695 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Astj zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. What is Hydrogen Embrittlement Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.
The inch-pound equivalents of SI units are given for informational purposes. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e.
Historical Version s – view previous versions of standard. Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels are highly aatm.
Mechanical Plating & Galvanizing
Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. Link to Active This link will always route to the current Active version of the standard. Samples should be tested for adhesion, aetm corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement.
Nonmagnetic Coatings on Magnetic Basis Metals. Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive astn chromates.
The thickest coating classes are usually referred to as “mechanically galvanized”. This abstract is a brief summary of the referenced standard. All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster.
Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required. Custom Industrial Processing, Inc.

Specializing in Mechanical Zinc Plating and Galvanizing Uniformity of thickness depends on part size and shape with typically thinner deposits v695 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.
CIP offers two post-plating services: CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.
