With the increasing maturity of domestic steelmaking technology, the total use of stainless steel has increased geometrically, and the thermos cups used in our daily life are made of stainless steel. But do you know what material you're using? There are two types of food-grade stainless steel on the market :304 stainless steel and 316 stainless steel. 304 stainless steel or 316 stainless steel, which is better? Please see our detailed explanation.
From the nickel content data, the nickel content of 304 is less than that of 316. In theory, the higher the nickel content, the better the corrosion resistance of the material itself. However, the current price of nickel alloy is relatively expensive, so the price of nickel is basically the main factor affecting the price of stainless steel, which is the law of the entire market, so each model will have specific product standards.
In the industry, the content of alloying elements in the material is usually used to determine whether the product is qualified. For example, 304 stainless steel, as long as the nickel content is greater than 8%, chromium content is greater than 18%, it is generally considered qualified. Therefore, 304 stainless steel is also known as "18/8 stainless steel".
Compared with 304 stainless steel, the molybdenum element is obviously added to 316 stainless steel, which can effectively improve the corrosion resistance and high temperature resistance of 316 stainless steel. It can be said that 316 can do 304 can do, 316 can do 304 can not do. Put bluntly, 316 stainless steel is actually an enhanced version of 304 stainless steel.
So put these two kinds of steel together, 304 stainless steel in addition to the price advantage, other aspects are slightly lower than 316 stainless steel. From the consumer's point of view, 316 stainless steel is definitely the choice of food machinery, kitchenware, medical equipment, but only if we can accept the relatively high price of 316; From the point of view of the manufacturer, 304 stainless steel is a choice for cost considerations, and for the relevant stainless steel products must also meet the national production standards, killing two birds with one stone.
In general, even if the 304 circulation on the market is relatively large, it is impossible to affect the true and correct answer, so the result does not need to be filled more, and the natural 316 stainless steel will win.
