Stainless steel is alloy product, as long as it is the stainless steel cup that meets national standard, among them various metal content index affects human health very little, this kind of cup holds ordinary boiled water under normal use, do not need to worry too much.
Common water cup stainless steel material has 304 stainless steel and 316 stainless steel, 316 in acid and alkali resistance, high temperature resistance ability is stronger than 304. Stainless steel cups are characterized by stainless rust.
For example, the vacuum cup adopts 316L stainless steel tank, composed of 18% chromium, 10% nickel, 2% molybdenum and iron. The nickel content is high, acid resistance and corrosion resistance are better than general stainless steel; Through complex process, the welding seam of the cup body is removed, and the oxide layer of the stainless steel surface is stripped by electrolysis technology, forming a smooth mirror inner wall for impurities and bacteria not easy to attach, and clean without residue is easier to clean. Thanks to the good ductility of 316L stainless steel, the 0.3mm liner is thin to 0.08mm. Compared with the products of the same grade, the inner wall thickness is reduced by 73%, the same capacity, the volume is smaller.
Xiao Wan has some suggestions here, such as do not hold some acidic drinks, such as fruit juice, coffee, carbonated drinks, including tea, soy sauce, vinegar, soup to avoid the corrosive body and the chromium metal harmful to human body.
