What Is The Difference Between 304 And 316 Stainless Steel?

304 and 316 are both stainless steel classifications. There is no difference in essence. They are all stainless steel, but there are differences in subdivision. 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 and alkali resistance, etc. 304 stainless steel is widely used in industrial and home decoration industries and food and medical industries. The kitchen utensils we use in our daily life are basically 304; the corrosion resistance, atmospheric corrosion resistance and high temperature strength of 316 stainless steel are better. 316 stainless steel is used in seawater equipment, chemical , dyes, papermaking, oxalic acid, fertilizers and other production equipment, photography, food industry, facilities in coastal areas, ropes, CD rods, bolts, nuts, if used in the food field, it is a bit extravagant.

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 spend 316 dollars to buy 304 appliances or spend 304 dollars to buy 304 appliances when we consume in the market. This is a question worth thinking about. First, it can be distinguished by the grade. The element formula corresponding to 304 stainless steel is 06Cr19Ni10; the element formula corresponding to 316 stainless steel is OCr17Ni12Mo2. The second is that we can tell the difference through stainless steel potion, and we can see it naturally after a drop, but this method is not very practical. You can't buy tableware with potion, and potion is also corrosive to tableware, so there are still many pots. Friends said that you can use a magnet to suck, but 304 stainless steel magnets can't suck, this is also a method, but this method is a bit inaccurate and not very reliable. 

In fact, when we buy tableware as consumers, 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 we buy it, as long as you can spend it It's worth buying the tableware you want at the price of 304. If the manufacturer sells it at a high price, then you have to think about it.
