Many polymeric compounds are nonreactive in both acidic and alkaline environments. However,
polymers generally lack the structural strength and resilience of metals. Nevertheless, for operations at

less than about 120°C in corrosive environments the use of polymers as liners for steel equipment or
incorporated into fiberglass structures (at moderate operating pressures) often gives the most economical
solution. The most common MOCs are still ferrous alloys, in particular carbon steel. Carbon steels are
distinguished from other ferrous alloys such as wrought and cast iron by the amount of carbon in them.
