As the name suggests, galvanized sheets are steel sheets coated with a layer of zinc, which to a certain extent provides corrosion resistance. This manufacturing method also helps reduce overall zinc consumption.
Introduction to galvanized sheet material and applications:
Galvanized sheets involve brushing a layer of zinc onto an iron plate for corrosion resistance, including cold and hot galvanizing methods.
Over time, the surface zinc will fall off, exposing the iron to corrosion. Stainless steel, on the other hand, does not require corrosion protection.
Naturally, it is more expensive, with stainless steel prices ranging between 200-300. Only a few special materials require low temperature tempering of 200-300 degrees.
However, under high temperatures (200 degrees, 300 degrees), the zinc layer on the galvanized sheet will gradually burn.
There are many types of stainless steel, while galvanized sheets simply involve electroplating a layer of zinc onto the surface of a steel or iron plate. Galvanized sheets are common plates with surface treatment, while stainless steel sheets are corrosion- and acid-resistant alloy plates.
Depending on your purpose, 200-300 degrees is not considered high temperature, and a relatively cheap 430 stainless steel plate should cost about twice the price of a galvanized sheet of the same specification.
Stainless steel achieves its corrosion resistance by adding trace elements to alter the composition of the steel.
Galvanized sheets, on the other hand, galvanize the surface of ordinary steel sheets, achieving corrosion resistance by sacrificing zinc. 200 and 300 degrees do not pose a problem for metals; depends on the ambient atmosphere. There may be some extremely small effects, but significant changes would take a long time to occur.
