304 stainless steel, the main component of all stainless steel is iron, a small part of the composition of carbon, nickel, chromium.
Because the composition of stainless steel is different, corrosion resistance is different, the name is naturally different.
304 stainless steel must contain 18% chromium and 8% nickel, 304 stainless steel is food-grade stainless steel, used in the home has been more than enough.
316 stainless steel added MO elements, corrosion resistance and acid resistance is better, widely used in medicine and industry, the price is more expensive, the general family will not use 316 stainless steel.
316 stainless steel acid and alkali resistance is certainly better than 304 stainless steel, the main reason is that the two composition content is different, 316 stainless steel MO element content is higher, MO corrosion resistance is very strong, so that 316 stainless steel corrosion resistance is better than ordinary stainless steel.
