Link to Active This link will always route to the current Active version of the standard. Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.

Mechanical Plating & Galvanizing

We also work with both Type I as coated, without supplementary treatment and Type II with asgm conversion treatment B specifications for special processing needs. Hot Dip Galvanizing Resin Impregnation. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.

It is the responsibility of the user of this standard to establish appropriate safety and health practices asmt determine the applicability of regulatory limitations prior to use.

Work Item s – proposed revisions of this standard.

The zinc b965 are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. All tests results should comply with the given requirements.

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 v695.

Electroplating The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement. The thickest coating classes are usually referred to as “mechanically galvanized”. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat.

This abstract is a brief summary of the referenced standard.

ASTM B – 04 Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel

Custom Industrial Processing, Inc. 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 inch-pound equivalents of SI asttm are given for informational purposes. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e.

The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.

What is Hydrogen Embrittlement Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. 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. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.

CIP offers two post-plating services: Nonmagnetic Coatings on Magnetic Basis Aetm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses.

Electroplating Mechanical Galvanizing vs.

Mechanical plating takes place g695 room temperature and does not induce hydrogen embrittlement of which hardened steels are highly susceptible. Historical Version s – view previous versions of 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 ashm post-plating finishes are applied if required.
