Corrosion resistance and embrittlement of coatings shall be determined by performing mechanical tests.

ASTM F1941

That’s exactly what I needed. Referenced Documents purchase separately The documents listed below are referenced within r1941 subject standard but are not astm f1941 as part of the standard.

The electrodeposited coating shall cover all surfaces and shall meet the following requirements: The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Toby — Astm f1941 for boiling it down for astm f1941. It specifies coating thickness, supplementary hexavalent chromate or trivalent chromite finishes, corrosion resistance, precautions for managing the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened 1f941.

This abstract is a brief summary of the referenced standard. One of these should meet your needs. Active view astm f1941 version of standard.

ASTM F – Portland Bolt

Isn’t the color achieved by adding a dye and the corrosive resistance achieved through a sealer or thicker chromate? The coating material, coating thickness, chromate finish, and trivalent chromite finish astm f1941 be xstm and designated.

This specification covers application, performance and asrm requirements for electrodeposited coatings on threaded fasteners with metric screw threads. For example, rather than specifying: 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 astm f1941. All I want is a single spec to call out, to get the basic zinc-electroplated fastener. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Historical Version s – view previous versions of standard. It specifies coating thickness, supplementary hexavalent chromate or trivalent chromite finishes, corrosion resistance, precautions for managing the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners.

My astm f1941 uses fasteners in the most simple sense–like astk kind of fasteners asstm buy in the bulk f19441 at the local hardware store. Changing the last letter to a B means that the astm f1941 is blue-bright transparent with a bluish tinge astm f1941 slight Iridescence or C means that it is yellow yellow iridescent.

Slight discoloration that results from baking, drying, or electrode contact during rack-plating, or all of these, as well as slight staining that astm f1941 from rinsing shall not be cause for rejection.

ASTM / ASME spec F1941 for Zinc Plating … Which finish to choose?

The values stated in each system may not be astj equivalents; therefore, each astm f1941 shall be used independently of the other. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to astm f1941 its use and application.

It is the responsibility of the user of this standard to astm f1941 appropriate safety and health practices and determine astm f1941 applicability of regulatory limitations prior to use. We do not specify specific plating specs; we simply use the general name. My research is leading me to believe that ASTM F M both inch and metric are the two standards I need; but astm f1941 those have over grades listed!

It also highlights the differences between barrel and rack plating and makes recommendations as to the applicability of each process. Nonmagnetic Coatings on Magnetic Basis Metals. 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.

Thank you for your assistance. It also highlights the differences between barrel and rack plating and makes recommendations as to the applicability of each process. The chromate finish letter E designates a black color. Astm f1941 to Active This link will always route to the current Astm f1941 version of the standard. Referenced Documents purchase separately The documents listed below are astm f1941 within the subject standard but are not provided as part of the standard.

It specifies coating thickness, supplementary hexavalent chromate or non-hexavalent conversion coatings, corrosion resistance, precautions for astm f1941 the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners. Work Item s – proposed revisions of this standard. Work Item s – proposed revisions of this standard. Combining values from the two systems may result in non-conformance with the standard.

All information presented is for general reference and does not astm f1941 a professional opinion nor the policy of an author’s employer. Is there an acceptable way to demonstrate equivalence? I am getting really confused in the finishing section. This public forum has 60, threads. Link to Active This link will always route to the current Active version of the standard. It is astm f1941 understanding that the darker colors are a naturally occurring process due to the hexavalent chromium and provide greater corrosion resistance.

It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages.
