The chromate finish letter E designates a black color. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. Toby — Thanks for boiling it down for me. This standard does not purport to address all of the safety concerns, if any, associated with its use. The testing frequency should initially establish and subsequently verify over time, the ability of a process to produce parts that do not have the potential for hydrogen embrittlement. See Section 10 and Appendix X1.

Your comments will receive careful consideration at a meeting of astk responsible technical committee, astm f1941 you may attend. 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. For internally threaded fasteners barrel-plating is generally suitable.

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

Isn’t the color achieved by adding astm f1941 dye and the corrosive resistance achieved through a astm f1941 or thicker chromate? December 9, Q. Current edition approved Jan.

Refer to Annex A1 for neutral salt spray performance requirements for zinc, zinc alloy and cadmium coatings. That standard should be consulted for more 1f941 information. Toby — Thanks for boiling it down for me. Test Method F is a recognized veri?

ASTM F1941

It assumes that the external thread pitch diameter is at the maximum and awtm the internal thread pitch diameter is at the minimum of the astm f1941 see Fig. The r1941 continuity is maintained between the parts by the rack itself. 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.

NOTE 1—Fasteners qstm a speci? For example, rather than specifying: This specification covers application, performance and dimensional requirements for electrodeposited coatings on threaded fasteners with metric screw threads. It should be noted that modi? Which finish to choose? Diameter Din.

Last previous edition F — The other dimensional characteristics shall be as speci? On an externally threaded fastener this occurs at the threaded tip. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This can 6 damage the external threads of fasteners. We do f141 specify specific plating specs; we simply use the general name. However the following restrictions apply: If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the f1491 shown below.

Corrosion resistance and embrittlement of coatings astm f1941 be determined by astm f1941 mechanical tests.

The testing frequency should initially establish and subsequently verify over time, the ability of a process to produce parts that do not have the potential for hydrogen embrittlement. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. Measuring astm f1941 thickness on the threaded portion of a fastener is possible but impractical for in-process quality control veri?
