Where 419 fits
Why 419 is special
Its low melting point and its ability to protect steel from rust are why galvanising works: steel is dipped in molten zinc at a temperature steel easily survives.

Related numbers & connections
Zinc melts far below steel, which is why steel can be dipped in molten zinc and come out coated and intact. Galvanising exists in the gap between those two melting points.

why?
Strength 0.50, confidence "high".
Science
Zinc melts at a temperature far below steel's, so steel can be dipped in molten zinc and emerge coated and undamaged. Galvanising depends entirely on that gap between the two melting points.
