AMS 2410 Technical Information

In accordance with AMS-2410, the customer purchase order MUST contain the following information:

  • Any pre-plate stress relief to be performed by AOTCO (time and temperature)
  • Desired plating thickness
  • Basis metal to be plated
  • Tensile strength or hardness of basis metal
  • Unique features, geometry, or processing on parts that requires special attention by AOTCO

This spec typically has a nickel strike between base metal and electrodeposited silver.

Silver plating is typically used to prevent galling and seizing of corrosion resistant steels.

All steel parts having a hardness of 40 HRC and above and which are machined, ground, cold formed or cold straightened shall be cleaned to remove surface contamination and thermally stress relieved before plating for the relief of residual tensile stresses. Residual tensile stresses have been found to be damaging during electrofinishing.

For parts having a hardness of 55 HRC and above, including carburized and induction hardened parts, stress relieve at 275 °F ± 25 °F (135 °C ± 14 °C) for a minimum of 5 hours.

For peened parts: If stress relief temperatures above 375 °F (191 °C) are elected, the stress relief shall be performed prior to peening or the cognizant engineering organization shall be consulted and shall approve the stress relief temperature.


Acceptance Testing

Acceptance test samples shall be randomly selected from all parts in the lot. A lot shall be all parts of the same part number, processed in a continuous series of operations (3.1 through 3.3), in not longer than 24 consecutive hours, and presented for processor’s inspection at one time. Unless the cognizant engineering organization provides a sampling plan, the minimum number of samples shall be as shown in Table 1.
