No, it’s can’t. Galvanized aluminum-magnesium steel plate and stainless steel 420 are different material types. The galvanized aluminum-magnesium steel plate is an alloy plate, mainly composed of zinc, aluminum magnesium, and other elements. It has high strength and corrosion resistance. Stainless steel 420 is a stainless steel material, mainly composed of elements such as chromium and carbon, and has good corrosion resistance and mechanical properties. Due to differences in composition and properties, galvanized aluminum-magnesium steel plates and stainless steel 420 are different in application and characteristics, so 420 cannot be used to make galvanized aluminum-magnesium steel plates.
