Active ast, current version of standard. All information presented is for general reference and does not represent a professional opinion nor the policy of an author’s employer.
Thickness shall be assessed either by microscopical method, a magnetic induction instrument, beta backscatter method, a micrometer, weigh-plate-weigh aastm, coulometric method, or X-ray spectrometry.
Does specifying embrittlement relief baking per Guide B replace Class 3 post heat treatment or should it be specified in addition to Class 3 post heat treatment? Call now or email.
Please fill out this brief form to access the free PDF download of U. Referenced Atsm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Since no high or low current densities exist, a very uniform thickness of deposits over irregular shapes can be achieved.
Visit our Resource Library for Design Recommendations.
Adhesion shall be examined either astn bend, impact, or thermal shock tests. Which of these would be performed first? Because the deposited nickel alloy is a catalyst for the reaction, the process is self-sustaining. Electroless Nickel plating ENalso known as autocatalytic nickel, is a micro crystalline to amorphous, hardenable nickel-phosphorous alloy coating.
It is informational only and not an official part of the standard; the full text of qstm standard itself must be referred to for its use and application.
If Asttm am coating primarily for corrosion protection, I can select a class 3 post heat aatm to improve adhesion and to provide for hydrogen embrittlement relief. Coatings with zstm contents greater than 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. Thanks for your help. Link to Active This link will always route to the current Active version of the standard.
This abstract is a brief summary of the referenced standard. February 24, — apologies, finishing. I figure that if I ask a plater to plate a part per a specification, the least I can do is read the specification and give them all of the ordering information they need to plate our parts per the specification.
Guide ASTM B is a better document to use as a guide to the adtm times for de-embrittlement operations, especially true when you get up the the high tensile strength or very hard materials.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
Coatings with phosphorus contents greater than This standard does not purport to address all of the safety concerns, if any, associated with its use. These coatings are used in electronic applications providing solderability, bondability, increased electrical conductivity, and resistance to strong alkali solutions. I’m an engineer trying to write good drawing notes for plating requirements.
What is the answer to the Heat Treatment vs. Medical device plated with a duplex coating of 0. The coatings shall be sampled and tested accordingly to evaluate both acceptance appearance, thickness, adhesion, asfm porosity and qualification requirements composition, microhardness, and hydrogen embrittlement. These coatings are used in applications requiring abrasion and wear resistance. The chemical and physical properties of the deposit vary primarily with its phosphorus content and subsequent heat treatment.
Some companies consider the high temperature bake as sufficient to replace the hydrogen embrittlement relief if it can be done within 4 hours, but you would need to check with your customer first before b373 down that route. The chemical asfm physical properties of the deposit vary primarily with its phosphorus content and subsequent heat treatment. 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.
They are also used for the salvage of worn or mismachined parts. USC offers a proprietary method – for applying electroless nickel to aluminum alloys. The chemical makeup of the plating solution and the use of the solution can affect the porosity and corrosion resistance of the deposit.

These coatings are used in applications requiring abrasion and wear resistance. The chemical makeup of the plating solution and the use of the solution can affect the porosity and corrosion resistance of the deposit. It offers a good barrier coating corrosion resistance. 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.
