✔Using 316 stainless steel is an alloy composed of a variety of metal elements, of which “chromium” is the most important element, because it will form a layer of chromium oxide protective film on the surface to achieve the effect of rust prevention. It must contain at least 11% “chromium” in order to be regarded as a true “stainless” steel, which has the characteristics of not being easy to rust. The other main ingredient is “nickel”, which is the best material for corrosion resistance.
