Galvanized And Stainless Steel Difference

Stainless steel costs four to five times as much as galvanized steel and untreated structural steel.
Galvanized and stainless steel difference. Galvanized steel is coated with a thin layer of zinc that helps guard against corrosion. It s commonly used in nails screws bolts nuts and other kinds of fasteners. Galvanized steel has the zinc layer on the surface level but in stainless steel chromium is dispersed inside the steel. Unlike galvanized steel stainless steel does not rust even when scratched since its protection is actually an integral part of it.
In addition visually stainless steel usually has a more matte surface than galvanizing especially if the stainless steel has not been subjected to a clean mirror finish. Niobium alloys are even more expensive. So when there is scratch galvanized steel tend to corrode whereas stainless steel can withstand for a longer period. What is the difference in price.
This means galvanized steel contains regular steel which is covered by zinc while stainless steel is made up of two separate metals mixed thoroughly together. Galvanized steel is almost the same price as untreated structural steel. This means that whenever it is scratched rusting immediately starts to occur around the scratched area. Galvanized steel is covered by a rust protective layer that is barely a millimeter thick.
Galvanized steel without crystallization patterns almost always has a mirror surface with a barely perceptible bluish tint.
