304 and 316 stainless steel which is good?
From the data of nickel content, the nickel content of 304 is less than 316, and in theory, the higher the nickel content, the better the corrosion resistance of the material itself. However, because the price of nickel alloy is relatively expensive at present, the price of nickel is basically the main factor affecting the price of stainless steel, which is the law of the entire market, so every model will have
From the data of nickel content, the nickel content of 304 is less than 316, and in theory, the higher the nickel content, the better the corrosion resistance of the material itself. However, because the price of nickel alloy is relatively expensive at present, 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. Like 304 stainless steel, under normal circumstances it is believed that as long as the nickel content is greater than 8% and the chromium content is greater than 18%, it can be identified as qualified, so 304 stainless steel is also called "18/8 stainless steel".
Compared with 304, 316 stainless steel obviously adds molybdenum element, and this element can effectively increase the corrosion resistance and high temperature resistance of 316 stainless steel, it can be said that 316 can do 304 can do 316, 304 can not do 316 can also do; Put bluntly, 316 stainless steel is actually an enhanced version of 304 stainless steel.
So put these two types of steel together, 304 stainless steel in addition to the price advantage, other aspects are slightly inferior to 316 stainless steel. If you stand in the consumer's point of view, whether it is food machinery, kitchen utensils, medical equipment, 316 stainless steel is definitely the first choice, but the premise is that we can accept 316 relatively high prices; If you stand on the point of view of the manufacturer, for cost considerations, 304 stainless steel is the first choice, but also in line with the national production standards for related stainless steel products, kill two birds with one stone.
