Buy insulation cup 316 steel or 304 steel?

As the "warmest little sun" in winter, preparing a thermos cup for yourself is of course essential. But do you really know the custom stainless steel insulated travel mug?

We often hear the term "ironmaking", the so-called "ironmaking", which is the separation of impurities from iron ore. The highest impurity in iron ore is carbon-so we use the carbon content as the standard for measuring iron.

Those with high carbon content (more than 2%) are called iron (also called pig iron); those with low carbon content (2% and below) are called steel (also called wrought iron). The higher the carbon content, the harder it is, but the more brittle it is-so the toughness of the steel is better, but the hardness is lower.

The common name of "steel iron" in steel may be more understandable to everyone-the iron in everyone's impression is probably not related to "not rusting". There are many types of steel, and stainless steel is just one of them.

Stainless steel vacuum insulated cups have many material specifications. The mainstream is 201/304/316/316 mirror stainless steel, which is an internationally recognized food-grade stainless steel. Compared with 304/316/316 mirror stainless steel, it is rust-proof. 2. Better corrosion resistance. So what's the difference between these kinds of materials?

304 is the most common stainless steel. Many kettles and word-of-mouth tea strainers are made of this material. The density of 304 stainless steel is 7.93 g / cm3, and the high temperature resistance of 800 ° C is widely used in the food and medical industries. Everyone calls it Food grade stainless steel, so the safety performance of 304 stainless steel is still very good. In addition, 3316 stainless steel, due to the addition of Mo, has greatly improved its corrosion resistance and high temperature strength. The high temperature resistance can reach 1200-1300 degrees, which can be used under harsh conditions.

316 mirror stainless steel (316L stainless steel), as a low carbon series of 316 steel, has the same characteristics as 316 steel, and has excellent resistance to grain boundary corrosion. Therefore, 316 stainless steel or 316 mirror stainless steel vacuum cups are the best choice for children's thermos cups, which can hold juice, milk and other drinks, while 304 stainless steel is best only filled with water.04 insulated cups cannot drink coffee because coffee is alkaline and will corrode the cup.

Stainless Steel Vacuum Insulated Cups

By comparison, at a glance, the 316 mirror stainless steel thermos cup is superior and more practical. Any beverage can be filled, but the price is high, so the 304 thermos cup is enough for general warm water, but if you usually use Inside is a variety of tea and milk powder, 316 mirror stainless steel insulation cup is the first choice, but if the price minds, you can buy 316 stainless steel insulation cup.

Finally, please note that when choosing a thermos cup, you must pay attention to whether the packaging or bottle is marked with the material used and whether the marked material is clear enough. The material of each accessory is very clear and clear at a glance.
