Carbon monoxide - Wikipedia
Carbon monoxide (CO) is a colorless, odorless, and tasteless flammable gas that is slightly less dense than air.It is toxic to animals that use hemoglobin as an oxygen carrier (both invertebrate and vertebrate) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.
Manganese controls oxygen and sulfur impurities in steel, increases the strength, toughness, hardness, and hardenability of steel, and inhibits formation of erittling grain boundary carbides. Normally, manganese metal is a brittle and unworkable substance; however, when alloyed in steels and other metals, it acts to produce tougher, harder, and stronger alloys.
