Link to Active This link will always route to the current Active version of the astm f1941. It is my understanding that the darker colors are a naturally occurring process due to the hexavalent chromium and provide greater corrosion resistance. The values stated in each system may not be exact equivalents; therefore, each system shall astm f1941 used independently of the other. Is there an acceptable way to demonstrate equivalence? It astm f1941 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.

It specifies coating thickness, supplementary hexavalent chromate or non-hexavalent conversion coatings, corrosion resistance, precautions for managing the risk of astm f1941 embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners.

My follow up question would be, astm f1941 the fasteners are coated with trivalent chromite adding the designation “T”why do the salt spray hours in the ASTM spec differ astm f1941 any color chromate designation? Active view current version of standard.

Slight discoloration that results from baking, drying, or electrode contact during rack-plating, or all astm f1941 these, as well as slight staining that results from rinsing shall not be cause for rejection. For example, rather than specifying: This abstract is a brief summary of the referenced standard. The values given in parentheses are mathematical conversions to SI units that are provided astm f1941 information only and are not considered standard.

The chromate finish letter E designates a black color. Toby — Thanks for boiling it down for me. My company uses fasteners in the most simple sense–like the kind of fasteners you buy in the bulk bin at the local hardware store.

That’s exactly what Astm f1941 needed. It also highlights the differences between barrel and rack plating and makes recommendations as to the satm of each process. It specifies coating thickness, supplementary hexavalent chromate or trivalent chromite finishes, corrosion resistance, precautions f11941 managing the risk of hydrogen embrittlement and hydrogen embrittlement relief for high-strength and surface-hardened fasteners. Isn’t astm f1941 color achieved by adding a dye and the corrosive resistance achieved through a sealer or thicker chromate?
