WebAll pure metals have stable melting points, for example, pure iron has a melting point of 2,800°F (1,538°C) because it has only one metallic element – “Fe”. Unlike pure iron, steel has a variety of metallic elements, and each alloying element usually has a specified content range, which results in steel alloys with a wide melting temperature range. WebA plastic kettle is therefore designed not to melt when water boils in it at 100°C. Typically, kettles are made of Polypropylene, or PP. PP has a melting temperature of 160°C, which means it starts to melt around 130°C. More than enough for a water boiler!
