... materials are normally classified as steels or low-alloy ferrous materials, high-chromium white irons or high-alloy ferrous materials, carbides, nickel-base alloys, or cobalt-base alloys. A few copper-base alloys are sometimes used for hardfacing applications, but for the most part, hardfacing alloys are...

... as chromium and titanium cannot be applied to steel by hot dipping because of their high melting points. Tin, which prior to 1937 was applied only by hot dipping, is now almost always electrodeposited. This is because it is very difficult to produce the thin and uniform coatings required for tinplate...
