Airport chairs of any material will not be eliminated. They will only say that the utilization rate is decreasing and the market demand is decreasing, but they will not disappear. Speaking of iron Airport chairs, iron row chairs are still used in many places. But we often call these steel chairs, or steel chairs. What is the reason?
First of all, we use chemical elements to illustrate:
Steel is a general term for iron-carbon alloys with a mass percentage of carbon between 0.02% and 2.11%.
Iron is a metal element, atomic number 26, chemical formula of iron: Fe.
Iron and steel are alloys of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements.
So in fact, it is unrealistic to call the iron airport chair directly. It is just an individual name on the market. We usually call it the steel airport chair or the steel Airport chair. The steel airport chair generally refers to the backplane of the airport chair is steel, and the armrest foot is steel/stainless steel/aluminum alloy, etc., because the armrest foot can be changed according to the demand of safflower.
