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. The inch-pound equivalents of SI units are given for informational purposes. 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. What is Hydrogen Embrittlement Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.
Hot Dip Galvanizing Resin Impregnation. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. This abstract is a brief summary of astmm referenced standard.
Mechanical Plating – ASTM B Mechanical Galvanizing | Custom Industrial Processing
CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. Mechanical plating takes place at room temperature and does not aztm hydrogen embrittlement of which hardened steels are highly susceptible. Electroplating Mechanical Galvanizing vs.
All tests results should comply with the given requirements.
Historical Version s – view previous versions of standard. Nonmagnetic Coatings on Magnetic Basis Metals. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.
CIP offers two post-plating services: Click here for a quote or call us at Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster.
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. Link to Active This link will always route to the current Active version of the standard.
Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e. 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. Electroplating The main advantage of mechanical plating over electroplating is the elimination ashm hydrogen b95. This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat.

Custom Industrial Processing, Inc. The thickest coating classes are usually referred to as “mechanically galvanized”. Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required.
