Galvanized And Stainless Steel Difference

So when there is scratch galvanized steel tend to corrode whereas stainless steel can withstand for a longer period.

Galvanized and stainless steel difference.

Unlike galvanized steel stainless steel does not rust even when scratched since its protection is actually an integral part of it. Niobium alloys are even more expensive. What is the difference in price. 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.

Galvanized steel has the zinc layer on the surface level but in stainless steel chromium is dispersed inside the steel. It s commonly used in nails screws bolts nuts and other kinds of fasteners. In general galvanized steel is more ductile and easier to work than stainless steel. Stainless steel is stronger and more corrosion resistant than galvanized steel.

Galvanized steel is coated with a thin layer of zinc that helps guard against corrosion. Galvanized steel without crystallization patterns almost always has a mirror surface with a barely perceptible bluish tint. This means that whenever it is scratched rusting immediately starts to occur around the scratched area. 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.

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