The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

Corrosion resistance and embrittlement of coatings shall be determined by performing mechanical tests. Toby — Thanks for boiling it down for me. Work Item s – proposed revisions of this standard. Which finish to choose?

That’s exactly what I needed. The chromate finish letter E designates a black color.

All information presented is for general reference and qstm not represent a professional opinion nor the policy of an sstm employer. Link to Active This link will always route to the current Active version of the standard. My follow up question would be, if the fasteners are coated with trivalent chromite adding the designation “T”why do the salt spray hours in the ASTM spec differ between any color chromate designation?

One of these should meet your needs.

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

For example, rather than specifying: Nonmagnetic Coatings on Magnetic Basis Metals. Work Item s – proposed revisions of this standard. Isn’t the color achieved by adding a dye and the corrosive resistance achieved through a sealer or thicker chromate?

Historical Version s – view previous versions of standard.

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

It is my understanding that the darker colors are a naturally occurring asrm due to the hexavalent chromium and provide greater corrosion resistance. 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 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! Combining values from the two systems may result in non-conformance with the standard.

Nonmagnetic Coatings on Magnetic Basis Metals. It specifies coating thickness, supplementary hexavalent chromate or non-hexavalent conversion finishes, corrosion resistance, precautions for managing the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners.

It also highlights the differences between barrel and rack asm and makes recommendations as to the applicability of each process.

December 9, Q. 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.

Is there an acceptable way to demonstrate equivalence? This specification covers application, performance and dimensional requirements for electrodeposited coatings on threaded fasteners with metric screw threads. This standard does not purport to address all of the safety concerns, if any, associated ff1941 its use.

We do not specify specific plating specs; we simply use the general name. This abstract is a brief summary of the referenced standard. The values stated in each system may not be exact astk therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance to the standard. The electrodeposited xstm shall cover all surfaces and shall meet the following requirements: The coating material, coating thickness, chromate f11941, and trivalent chromite finish shall be selected and designated.
