I can't deny that I don't miss those times.
Stainless steel is defined as an iron-carbon alloy. Stainless steel does not stain, corrode or rust as easily as ordinary steel (it "stains less"), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the aviation industry. Common uses of stainless steel are cutlery and watch straps.High oxidation-resistance in air at ambient temperature are normally achieved with additions of a minimum of 13% (by weight) chromium, and up to 26% is used for harsh environments. Therefore, we will be usins stainless stell for some parts of the playground. Since some people have sensitive skin, stainless steel is suitable for the children from getting skin diseases. Rubber can be used to cover the metal from burning their hands when the day is hot.
