What is the difference between 304 and 316 stainless steel?

Latest company news about What is the difference between 304 and 316 stainless steel?

As a business person in a stainless steel company, it is simply not easy to answer such a question. I cannot answer it in a professional and in-depth manner, but it is still ok to give a simple explanation. 304 and 316 are both stainless steel classifications. There is essentially no difference. They are both stainless steel, but there are differences when broken down. The quality of 316 is higher than that of 304. 316 steel adds Mo on the basis of 304. This element greatly improves the corrosion and wear resistance of stainless steel. First of all, 304 stainless steel has good processing performance, high toughness, high density, no bubbles in polishing, acid resistance, alkali resistance, etc. 304 stainless steel is widely used in the industrial and home decoration industries and the food and medical industries. The kitchen utensils, pots, pans, and cups we use in our daily lives are basically all made of 304; while 316 stainless steel has better corrosion resistance, atmospheric corrosion resistance, and high temperature strength. 316 stainless steel is used in seawater equipment, chemical , dyes, papermaking, oxalic acid, fertilizer and other production equipment, photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts, it is a bit luxurious if used in the food field. Secondly, the density of 304 stainless steel is 7.93g/ ㎝³; The density of 316 stainless steel is 8.03g/㎝³. Furthermore, as consumers, we are more concerned about whether we spent 316 dollars to buy 304 appliances or spent 304 dollars to buy 304 appliances when we were consuming in the market. This is a question worth thinking about. First, it can be distinguished by the grade. The corresponding element formula of 304 stainless steel is 06Cr19Ni10; the corresponding element formula of 316 stainless steel is OCr17Ni12Mo2. Second, we can distinguish it through stainless steel potion. Just put a drop on it and you can see it naturally. However, this method is not very practical. You can’t buy tableware with the potion, and the potion is also very corrosive to the tableware. There are still many pots. Friends said that you can use a magnet to suck it, but 304 stainless steel magnets cannot suck it. This is also a method, but this method is a bit inaccurate and not very reliable. In fact, when we as consumers buy tableware, we don’t need to pay too much attention to whether it is 304 or 316, because the performance of 304 can fully meet the performance of our tableware, so if you buy it, as long as you can spend it It's worth buying the tableware you want for the price of 304. If the manufacturer sells it at a higher price, then you have to think carefully about it.
