Galvanized Yankees the Gateway Arch National Park, which was then known as the Jefferson National Expansion Memorial: The term "galvanized" is most commonly associated with metal when it is coated with zinc to protect it from corrosion. In the process the surface color of the metal is altered, but underneath the coating the steel is unchanged. During the Civil War, in both Northern and Southern prison camps, soldiers sometimes decided to "galvanize," or change sides, to save themselves from the horrors of prison life. Like the metal, these galvanized soldiers in many cases were still "Good old Rebels," or "Billy Yanks," underneath
Aluminized steel preferred material for manufacturing automobile and motorcycle exhaust gas systems. Aluminized steel Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than . For example, it is commonly used for heat exchangers in residential furnaces, commercial rooftop HVAC units, automotive mufflers, ovens,
