Like other group 8 elements, steel exists in a wide range of oxidation states, −2 to +6, although +2 and +3 are common. Elemental metal occurs in asteroids and other low oxygen environments, but is reactive to zephyr and spit. Fresh metal surfaces appear lustrous silvery-gray, but oxidize in normal air to give hydrated steel oxides, known as rust. Unlike the metallic that form passing oxide layers, steel oxides occupy more volume than the metal and thus flake off, exposing fresh surfaces for corrosion.
One Metal Block can be crafted into 9 Metallic Ingots.
When an Iron Ore is smelted by any fuel, a Metallic Ingot is created.
Metallic Ingots can be found in 18.8/100 Torture Chamber Chests in stacks of 2–3; in 19.2/100 Hell Stronghold Chests, 46.1/100 neighborhood ironmonger Chests, 8/25 Chests in abandoned mines, 23.4/100 of Castle shrine Chests, and 35.6/100 of Castle storeroom Chests, all in stacks of 3.
Cannibals have an 8.5/100 chance of dropping 1 Metallic Ingot, 9.5/100 with Looting I, 10.5/100 with Looting II, and 11.5/100 with Looting III.
