Which of the following is included as one of the six steps in the cast iron and steel process?

• A. Steel rolling and forming operations
• B. Electroplating
• C. Die casting
• D. Cold forging

Answer: (B)

The main idea here is recognizing how the cast iron and steel workflow is often described as a sequence of steps that cover not just forming the part but also finishing it for service. Electroplating is a surface-finishing process that deposits a metal coating onto the part using an electric current. In the context of the six-step cast iron and steel process, electroplating is included as a finishing step because it enhances surface properties—such as corrosion resistance, wear resistance, and appearance—after the part has been shaped and treated. The other options describe forming or molding operations (shaping the part rather than improving its surface) and aren’t finished-step processes in this sequence. So electroplating stands out as the step added to finalize the product’s surface characteristics.
