Terne-coated stainless steel is type-304 stainless coated with a lead-tin alloy.

• A. True
• B. False
• C. Stainless steel is not used in terne applications
• D. It is coated with zinc

Answer: (A)

Terne coating refers to applying a lead-tin alloy as a surface finish to a metal to give solderability and corrosion resistance. The coating is specifically a tin-lead alloy, not zinc. Stainless steel, such as type-304, can be used as the substrate for a terne coating, producing terne-coated stainless steel. So the statement is true because the finish is a lead-tin alloy, not zinc, and stainless steel can be the base material.
