Purpose

This specification covers the requirements for electrodeposited cadmium plating.

Application

The electrodeposited cadmium platings covered by this specification are intended for use as corrosion protective coatings. Unless otherwise specified, components heat treated to an ultimate tensile strength greater than 200 ksi (1379 MPa) or harder than 43 HRC should not be plated in accordance with this specification. Section 5 contains more information about the appropriateness of this process and the coating material. It also describes alternatives to cadmium plating.

Classification

Cadmium plating shall be of the following types and classes, as specified (see ordering information):

Types

I - As plated

II - With supplementary chromate treatment (see 3.2.9.1 and 3.2.9.2) Grade A - Hexavalent chromate treatment, maximum service temperature 250 °F (121 °C) Grade B - Hexavalent chrome free treatment, maximum service temperature 375 °F (191 °C)

III - With supplementary phosphate treatment (see 3.2.9.3)

For Type II plating, if no grade is specified, Grade A shall be supplied. Processors shall have the option to use Grade B if permitted by the cognizant engineering organization.

Type II, Grade A may be listed as Type IIA and Type II Grade B may be listed as Type IIB; the terms are equivalent.

Classes

1 - 0.0005 inch (0.0127 mm), minimum

2 - 0.0003 inch (0.0076 mm), minimum

3 - 0.0002 inch (0.0051 mm), minimum

Safety-Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
