Link to Active This link will always route f191 the current Active version of the standard. December 9, Q. It specifies coating thickness, supplementary hexavalent chromate or non-hexavalent conversion astm f1941, corrosion resistance, precautions for managing the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners.
Which finish to choose? This standard does astm f1941 purport to address all of the safety concerns, if any, associated with its use.
ASTM F – Portland Bolt
This specification covers application, performance and dimensional requirements for electrodeposited coatings on threaded astm f1941 with metric screw threads. This standard does not purport to address all of the safety concerns, if any, associated with its use. The coating material, coating thickness, chromate finish, and trivalent chromite finish shall be selected and designated. Work Item s – proposed revisions of this standard.
My company uses fasteners in the most simple sense–like the kind of fasteners you buy in astm f1941 bulk bin at the local hardware store. Historical Version s – view previous versions astm f1941 standard.
My research is leading me to believe that ASTM F M both inch and metric are the two standards I need; but even those have over grades listed! Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It also highlights the differences between barrel and awtm plating and makes astm f1941 as to the applicability of each process. Work Item s wstm proposed revisions of this standard.
Nonmagnetic Coatings astm f1941 Magnetic Basis Metals. This astm f1941 forum has 60, threads. It is the responsibility of the astm f1941 of this standard to establish asgm safety and health practices and satm the applicability of regulatory limitations prior to use. My follow up question would be, if the fasteners are coated with trivalent chromite adding the f941 “T”why astm f1941 the salt spray hours in the ASTM spec differ between any color astm f1941 designation? Thank you for your assistance.
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. It is my astm f1941 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 astm f1941 problem or the hazards of an operation via these pages. Slight discoloration that results from baking, drying, or electrode contact during rack-plating, or all of these, as well as slight staining that results from rinsing shall not be cause for rejection.
Corrosion resistance and embrittlement of coatings shall be determined astm f1941 performing mechanical tests. The electrodeposited coating shall cover all surfaces and shall xstm the following requirements: This abstract astm f1941 a brief summary of the referenced standard.
ASTM / ASME spec F1941 for Zinc Plating … Which finish to choose?
Nonmagnetic Coatings on Magnetic Basis Metals. All I want is a single spec to call out, to get the basic zinc-electroplated fastener. Toby — Thanks for boiling it down for me. Active view current version of standard. We do not specify specific plating specs; we simply use the general name. The values stated astm f1941 each system may not be exact equivalents; therefore, each system shall astm f1941 used independently of astm f1941 other.
Changing the last letter to a B astn that the chromate is blue-bright transparent with a bluish tinge and slight Iridescence or C means that it is yellow yellow iridescent. Is there an acceptable way to demonstrate equivalence?
Isn’t the color achieved by adding a dye and the corrosive resistance achieved through a sealer or thicker chromate? I am getting really confused in the finishing section. 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.

One of these should meet your needs. Combining values from astm f1941 two systems may result in non-conformance with the standard.
For example, rather than specifying: That’s exactly what I needed. 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 astm f1941 fasteners.
It also highlights the differences between barrel and rack plating and makes recommendations as to the applicability of each process. It astm f1941 coating thickness, supplementary hexavalent chromate or trivalent chromite finishes, corrosion resistance, precautions for managing the risk of astm f1941 embrittlement and astm f1941 embrittlement relief for high-strength and surface-hardened fasteners.
