General thermos cups are made of 304 stainless steel, which is weak in corrosion resistance and easy to corrode acid-base beverages such as coffee and milk. However, if it is an ultra-light thermos cup with a cold water mirror liner like that in the United States, it is made of 3 16 stainless steel, so don't worry at all.
Introduction of 3 16 stainless steel thermos cup.
The 3 16 stainless steel thermos cup itself is safe and hygienic, and it is mainly to pay attention to some things that are not suitable for soaking the thermos cup in daily use. 304 stainless steel is suitable for food grade, and 3 16 is higher than 304. 3 16 is mainly used for medical equipment. Of course, it can also be used on first-class and second-class tableware, but the cost is slightly higher.
3 16 stainless steel thermos cup is harmless. 3 16 stainless steel is austenitic stainless steel. With the addition of Mo, the corrosion resistance and high temperature strength are greatly improved, and the high temperature resistance can reach 1200- 1300 degrees, so the thermos cup made of 3 16 stainless steel is harmless.
Generally, 304 stainless steel and 3 16 stainless steel are the most commonly used materials for thermos cups. Stainless steel is the most common steel, which can withstand the high temperature of 800 degrees Celsius, and has excellent corrosion resistance and intergranular corrosion resistance.
Good processability, high toughness and weak magnetism. 3 16 stainless steel has better corrosion resistance and high temperature resistance due to the addition of molybdenum. High temperature resistance can reach 1200- 1300 degrees, and it can be used in harsh and cool conditions without magnetism.
