Galvanized And Stainless Steel Difference

In general galvanized steel is more ductile and easier to work than stainless steel.

Galvanized and stainless steel difference.

Stainless steel is stronger and more corrosion resistant than galvanized steel. 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.

It s commonly used in nails screws bolts nuts and other kinds of fasteners. Galvanized steel is prepared by adding a layer of zinc coating to its surface to prevent corrosion while stainless steel is mixed with ten percent or more of chromium in its molten state. Galvanized steel has the zinc layer on the surface level but in stainless steel chromium is dispersed inside the steel. Galvanized steel without crystallization patterns almost always has a mirror surface with a barely perceptible bluish tint.

So when there is scratch galvanized steel tend to corrode whereas stainless steel can withstand for a longer period. Unlike galvanized steel stainless steel does not rust even when scratched since its protection is actually an integral part of it. Galvanized steel is coated with a thin layer of zinc that helps guard against corrosion. Niobium alloys are even more expensive.

Stainless steel costs four to five times as much as galvanized steel and untreated structural steel.
