Any airport chair material will not be eliminated, only speak utilization rate drop, fall in demand for the market, but it is not going to disappear.
Speaking of iron airport chair, many places are still is to use iron seating.
But we often call these steel seating, or steel seating.

02% to 2.
Between 11% iron carbon alloy.
Iron is a kind of metal elements, atomic number 26, iron elemental chemical formula: Fe.
Steel is iron and carbon, silicon, manganese, phosphorus, sulfur, and small amounts of other elements of the alloy.
