What is the Stainless Steel Cladding?

The stainless steel cladding is very durable and resistant to environmental effects.The stainless steel contains a good proportion of chromium (minimum 10%) which reacts with oxygen to form a passive layer of chromium oxide (Cr2O3) which is non-porous and restricts further corrosion.Stainless steel cladding can be used on carbon steels and Why Does Stainless Steel Rust?·Stainless steel can contain other elements such as nickel and manganese,but chromium is the key element which makes it rust resistant.When the surface of normal steel is exposed to oxygen,it usually forms ferric oxide (Fe 2 O 3) which has the well-known red rust color.Ferric oxide doesnt form a continuous layer on the steel because the Will stainless steel 304 rust?Jun 06,2013·A.Re the rusting of a stainless steel cabinet --Some years ago I worked for a company producing food-handling equipment.A customer complained some units were rusting.On investigation we discovered that the contractor who grit-blasted our unfinished products had used grit previously used for treating ordinary mild steel items.
